Why do rashes appear randomly at highly specific locations (and not others), without location specific triggers? Like, if it's a systemic issue, then it should be distributed to other areas on the body too.
What does an HIV rash look like?
A rash can be an early symptom of HIV, but HIV can also increase the risk of developing different types of rashes.
People who develop a rash and believe they may have had exposure to HIV should seek medical advice. If an HIV infection is present, treatment can help manage it effectively.
HIV transmits from one person to another when bodily fluids come into contact with each other. These include blood, semen, rectal and vaginal fluids, and breast milk.
Exposure to HIV can happen if a person has sex or shares needles with someone who has the virus.

No single rash is specific to HIV. As HIV involves changes in the immune system, it can trigger a variety of skin reactions.
However, the rash that occurs at the early stage usually involves flushed, discolored, or reddish, flat blemishes that do not itch, according to one source.
A rash can be an early sign of HIV, occurring as a result of seroconversion. This is the acute, or early stage of HIV, which occurs within 1–2 weeks of exposure to the virus.
During the seroconversion or acute HIV stage, the body produces antibodies to the virus. Between half and 80–90% of all people with HIV experience flu-like symptoms at this stage and some people may develop a rash.
Sometimes, a rash is the only symptom of HIV, but because HIV impacts the immune system, there are often other symptoms, too.
Early symptoms of an HIV infection that can occur alongside a rash include:
- muscle aches
- night sweats
- sore throat
- generally feeling unwell
- a fever
- swollen lymph nodes
- mouth ulcers
According to the Centers for Disease Control and Prevention (CDC), these symptoms may appear 2–4 weeks after exposure and last between a few days and several weeks.
Anyone who experiences these symptoms after possible exposure to HIV should seek advice about testing.
If a rash occurs as a symptom of the acute stage of HIV, it will usually go away as the immune system produces antibodies to HIV.
After this, however, if a person is not taking medications to control HIV, they may have a higher chance of developing further rashes and skin problems. This is because HIV leads to a weakened immune system.
When the immune system is compromised, it becomes easier for viruses, fungi, bacteria, parasites, and other causes to trigger a rash.
Conditions that may appear with skin symptoms include :
- Molluscum ecthyma
- furuncles and carbuncles
- verrucae, warts, and papules
- non-melanoma skin cancer
- seborrheic dermatitis
- bullous impetigo
- drug reactions
In some cases, treatment for HIV can trigger an allergic skin reaction.
The following images here show some ways in which HIV may affect the skin.
A rash that appears during seroconversion will usually disappear without intervention, but other types of rash may occur later.
HIV-related rashes vary greatly. The chance of developing a rash will depend on factors such as:
- overall health
- use of antiretroviral drugs
- access to medical care
- exposure to contagious skin conditions
Chronic skin conditions
In time, other rashes can develop due to chronic conditions, such as herpes and psoriasis. These are long-term conditions that do not go away completely, although the symptoms may improve or disappear for a while.
The severity of each outbreak varies but depends partly on the immune function. Some medications, such as antiviral drugs for herpes, can reduce the severity of each outbreak.
Acute skin conditions
Rashes that result from an infection will go away with appropriate treatment.
However, due to HIV’s impact on the immune system, infections can become more likely. A previous rash may return, or a new one may appear.
Drugs for treating HIV can sometimes trigger a rash. Anyone who believes they have a rash due to their medication should speak to a member of their healthcare team. It is often possible to switch to another drug.
It is essential to speak to a doctor before changing or discontinuing treatment.
Taking antiviral medication keeps viral levels low and reduce HIV’s impact on the immune system. Many people can now live a healthy life with HIV, but it is essential to follow the treatment plan.
097: Are Your Rashes Triggered By A Salicylate Sensitivity? [FULL TRANSCRIPT]
Welcome back to episode #97 of the Healthy Skin Show!
In today's episode, I wanted to talk to you about phytochemicals called salicylates.
If you've been dealing with skin rashes for some time, you may have heard of the low Salicylate diet and some people may have suggested that you give it a try.
The question is, is it worth it to give the diet a try and what does reacting to salicylates really mean?
If you can't tolerate salicylates, you're probably going to be surprised because it's not what most people think.
What Are Salicylates?
Before we get ahead of ourselves, let's talk about what salicylates are!
Salicylates are naturally-occurring phytochemicals that exist in plants. Some plant foods have a higher quantity of Salicylates in them.
The amount of salicylates present is food is not the result of cooking a certain type of food for a period of time.
Nor is it something that is sprayed on the plant while it's being cultivated by a farmer like fertilizer or some sort of herbicides. It is naturally-occurring inside of the plant itself.
Take white potatoes as an example — they are considered to be high in salicylates! One exception many people don't know is that the salicylates are concentrated in the skin. Removing the skin actually drops the salicylate content of the potato flesh to a low level.
When you look online, some websites will claim that salicylates are really bad for you or even toxic! In some instances, I've seen websites claim that salicylates will kill you… and that is not the case.
Salicylates are (for the most part) naturally-occurring in plants (fruits & veggies) with one exception. Aspirin (and any drugs that contain aspirin) contain salicylic acid as its main ingredient.
Aspirin is the pharmaceutical version of the botanical agent called Willow bark. Willow bark, when digested in your gut, produces salicylic acid.
Are Salicylates In Food Bad For You (And Your Rashes)?
So if salicylic acid or salicylates are naturally occurring, then can they be bad for you?
Well, it is possible to have a salicylate allergy potentially ending up with anaphylaxis. But that's a very small number of people.
When we discuss salicylates in terms of skin rashes and dietary changes, we're talking about salicylate sensitivity or salicylate intolerance.
And this is where things get a bit murky because being sensitive to salicylates means that you don't have a gut problem.
You have a liver detoxification problem.
We're used to thinking of intolerances and sensitivities as a food-digestive-gut problem, but in this particular case, that's not accurate.
Salicylates are not proteins that would normally be the culprit behind a sensitivity or intolerance. They're not processed in the digestive system in the same way that proteins typically are.
Because they're a phytochemical., they go to the liver which will end up processing them.
So if you react to salicylates, it's a clue that your liver needs support… not that you have a gut problem.
This also does not mean that your liver needs to be detoxed. There are natural detoxification pathways in your liver ready and able to do the task at hand.
If you're not clear on your liver's Phase II Detox pathways, check out episode #47 where I dive pretty deep into the whole process of liver detoxification.
Your Liver Deals With Salicylates — Not Your Gut
What is most imperative for you to know is that any salicylates you eat head straight to your liver. Your liver sends them down Phase II detox pathways in order to be processed.
Most of the salicylate load is processed through the glycine pathway, which requires glycine and vitamin B6.
A smaller portion is processed through the glucuronidation pathway.
It's not that your gut can't handle the salicylates in the foods which is what most people think.
Instead, if you seem to have a skin rash flare-up after consuming high salicylate foods, it's a clear sign that your liver needs support.
It doesn't mean that you necessarily need to remove high Salicylate foods. The low salicylate diet is in and of itself is a bandaid.
It's not addressing the root cause of the problem which is your liver doesn't have the nutrients available to it to process the salicylates in the first place.
See, these pathways in the liver are nutrient-dependent. If you don't have enough of these specific nutrients available for the liver to work with, detox pathways slow down to a snail's pace.
Another problem with the low salicylate diet is that it's very restrictive.
By unnecessarily cutting out so many foods, you reduce diversity and nutrient-density. And as a result, you can find yourself in a bit of a jam.
Unsurprisingly, many clients of mine have tried a low salicylate diet and seen next to no improvement at all.
If that's been your experience, then salicylates probably aren't your problem and I would recommend beginning to add them back into your diet.
[Nervous about reintroducing foods that you cut out WITHOUT triggering a skin rash flare? READ MORE HERE]
Though it's not common, there can be instances where someone may have some genetic SNPs that impact the functioning of these liver enzymes.
If you believe that you might have some sort of SNP impacting the Phase II Detox pathways, it may be worthwhile to sit down with a doctor who understands genetic information.
How To Support Your Liver If You Have Salicylate Sensitivity
My recommendation if you believe that you have salicylate sensitivity is to focus on supporting your phase II liver detoxification pathways.
The particular pathways in question include the glycine pathway and glucuronidation.
First, glycine and vitamin B6 are necessary to support the Glycine pathway.
As for vitamin B6, the active form is preferable typically called P5P.
Before supplementing with higher doses of Vitamin B6, consult with a practitioner. You can over-supplement B6 and cause some very unpleasant symptoms.
Second, certain foods may be helpful to support proper glucuronidation. Cruciferous vegetables and citrus are great options to add to your diet daily.
I realize that citrus can be a trigger for people with skin rashes as some find it can trigger a flare.
And you can also try adding in a daily cup of rooibos tea (which is naturally caffeine-free).
Unfortunately, there isn't a lot of research out there that exactly pinpoints the best food to support glucuronidation. I feel like it's safe to say that more research is needed!
In some instances, there's conflicting information about what supports glucuronidation and what slows it down. Studies done in test tubes and human beings haven't always matched up.
I have had good luck supporting clients who are sensitive to salicylates with supplementation. I recognize that some people prefer to deal with health issues through diet. You can try adding in some of these foods and see if this makes an improvement.
If not, you may need more than what your diet provides from a nutritional perspective.
And if you're not properly absorbing the nutrients, supplementation may be warranted. THIS is one of the Phase II detox support supplement that I use in my clinical practice.
Got any questions or comments? Leave them below so we can keep the conversation going!
If someone you know has been thinking that they've got to eliminate all these foods and they are freaking out…
Or they're really miserable on a low salicylate diet (especially that they haven't seen any results on it), share this episode with them.
This could be really helpful for them to realize that a low salicylate diet is not necessary to help them support their skin.
Thank you so much for tuning in and I look forward to seeing you in the next episode!

4. Family History Of Lichen Planus
A rare kind of lichen planus called familial bullous lichen planus is known to run in families. However, do keep in mind that other kinds of lichen planus do not appear to be hereditary. 6
One study found that the shin is most commonly affected in familial bullous lichen planus, after which come the upper limbs and thighs. This kind of lichen planus tends to be chronic and progressive. It also usually doesn’t involve the torso and the mouth. 7
An Allergist Explains Why You Might Be Itchy All Over, Even Though You Don’t Have a Rash
As an allergist/immunologist, I see patients to help them diagnose and treat a variety of medical problems, ranging from allergies to lupus and other immune system disorders. Something that always surprises me in my job is how many of my patients are willing to “just live” with some of the symptoms they come to me with, like a seemingly basic rash or mild swelling from an allergic reaction. Even after living in discomfort for far longer than they should, it seems like they assume the symptom is pretty normal, so they don’t seek out an opinion from someone who could help.
A patient might come to me and say, “I have been feeling strangely itchy for a while now, but it’s probably nothing, right?” While it’s possible that body itchiness—the medical term for it is pruritus—with no rash may be related to something super minor, like dry air in the winter or skipping the moisturizer, there are also many other possible, lesser-known causes for feeling itchy that may require specialized treatment. And you should never just dismiss a very persistent symptom—even if it seems like no big deal—without a proper workup.
Below are some reasons you may be feeling itchy, even when there is no rash present.
Dry skin, as you probably know, is an obvious reason to be itchy. But the appearance of your skin when you feel itchy, before you touch it and make it red by scratching, can help you figure out if you’re dealing with normal dry skin that really just craves moisture, or something else.
Typical (untouched) dry skin tends to appear ashy. Now, if you are itchy in spots that do coincide with a visible rash, you may be dealing with another skin issue, such as psoriasis or contact dermatitis (which is when the skin reacts after coming in contact with a substance that irritates it, like a detergent). If you have a rash that’s not going away, see your doctor, who can refer you to an allergist and/or dermatologist if necessary.
Back to dry skin: Staying hydrated and not overwashing can help address the dryness and, in turn, stop the itch. And don’t forget to moisturize. Moisturizers act as a barrier to seal in moisture and also hydrate the skin, but some formulas work better than others for dry skin. You’ll want to choose a heavier moisturizer, like an oil-based cream, which will more effectively lock in moisture.
A little shopping hint: Heavy-duty creams are often sold in tubs versus pump bottles because they can be too thick to pump out—so look for tub packaging.
If you have noticed that your body itchiness began after starting a new medication, then that may be the culprit. Certain medications like statins (which are used for cholesterol), blood pressure-lowering medications, and opioids are all known to naturally evoke an itchy sensation that’s not necessarily accompanied by any skin lesions. The exact mechanisms behind drug-induced pruritus for different medications are not entirely clear and may depend on the specific drug. Itchiness in general isn’t a topic that’s considered well-studied at this point.
In some cases, the itchiness will clear up spontaneously if you stop taking the drug. Speak with your doctor if the onset of your itchiness may correlate with a new medication you’re taking. They can consider switching you to a different medication, if it’s an option in your individual case.
Body itchiness is a well-known symptom related to hyperthyroidism and hypothyroidism. But itchiness would likely occur in addition to other common thyroid-related symptoms, including changes in weight and/or appetite and fatigue. Your primary care physician or an endocrinologist can do a blood test to check for any abnormality of your thyroid function and possibly a physical examination of your thyroid gland to check for swelling or tenderness.
Pruritus can be a sign of kidney disease, and it usually shows up when the disease is in an advanced stage. The kidneys are responsible for filtering the blood and removing excess fluid and toxins from the body but when they no longer function properly, the blood may be filled with abnormally high amounts of waste that they couldn’t filter out (this is called uremia).
As I’ve mentioned, the pathology of pruritus as it relates to different health conditions is far from understood. But with kidney failure, it’s possible that pruritus has to do with inflammation or an imbalance of electrolytes and nutrients in the blood, as the National Kidney Foundation explains.
Take note of where you feel itchy on your body, like whether it’s all over or more localized. People with itchiness tied to kidney disease generally feel the most itchy on their back, but it’s also not unusual for them to feel itchy on the head, abdomen, and arms as well.
Cholestasis is a condition that occurs when there’s an issue with the flow of bile (a digestive fluid) in the body, and it can be tied to certain liver or pancreatic diseases or occur when there’s a problem with the bile duct. When cholestasis happens, waste product known as bilirubin gets into the bloodstream.
This action can cause itchiness, possibly due to the bilirubin building up in the skin.
Cholestasis can also occur during pregnancy (especially in the third trimester), as SELF reported previously. Cholestasis of pregnancy can be dangerous or even life-threatening to the baby—so it’s crucial to get any persistent itchiness checked out right away by your physician if you are pregnant. (Itchiness is the main symptom used to diagnose cholestasis of pregnancy, but other signs may include jaundice, nausea, and loss of appetite, per the Mayo Clinic.)
Treatment for cholestasis depends on the underlying cause, but there are medications that can help alleviate itchiness that your doctor may prescribe.
A pinched nerve, which is when there’s pressure put on a nerve by bone or cartilage or other tissues around it, can stimulate a tingly sensation or numbness that some people may describe as itchiness. The itchy feeling may not occur directly where the pinched nerve is located for instance, if you feel tingly near the upper forearm area, it could be due to nerve compression in the neck. You may also be dealing with brachioradial pruritus, which is characterized by a tingling or “burning” in the shoulder, neck, or forearm. (The cause is unknown but may have to do with sun exposure.)
Cold compresses applied to the area may be helpful to temporarily relieve the discomfort, but the itchiness may persist as long as the nerve issue itself does.
Other conditions involving the nervous system—shingles, multiple sclerosis, and diabetes, to name a few—can also trigger an itching or tingling, too. This is what experts refer to as “neuropathic itch,” but research that helps explains why this phenomenon occurs is limited.
Cancer is not as common of an etiology when it comes to itchiness without a rash, but certain types of cancer including lymphoma, pancreatic cancer, and blood cancers are linked to this symptom. Unusual body itchiness in some cases can even help lead to a cancer diagnosis. (Some people deal with pruritus as a side effect of cancer treatment, like chemotherapy, but it can also be due to the cancer itself.)
People with human immunodeficiency virus (HIV) can deal with itchiness without (or with) a rash on the body, too. This can be due to the virus itself, or a side effect of medication.
Body itchiness can wax and wane. But if you’ve noticed an itchy sensation for two weeks or longer, have any other symptoms, or if you’re feeling really uncomfortable and don’t want to wait, bring it up with your doctor. Sometimes you can fix itchiness on your own (using over-the-counter treatments for dry skin or an antihistamine, perhaps). But in some cases, like if you’re dealing with a thyroid disorder, you need to treat the underlying medical condition, not just the itchy sensation.
In preparation for your appointment, it’s important to take note of whether or not you notice a rash before you feel itchy, or if you are itchy and then you develop redness or a rash from scratching. Though this detail seems minor, as an allergist/immunologist, it actually dramatically changes the way I will try to pinpoint the cause, and what type of other specialist I might loop you in with.
The bottom line: You deserve to feel well and be comfortable. And body itchiness is probably not something that you’d call comfortable—it’s frustrating and can mess with your ability to sleep, not to mention your overall quality of life. So, treat ongoing itchiness as a symptom that deserves proper medical attention.

Probable Causes of Red Skin
1 – Sunburns
Sunburns are common among people who spend a lot of time in the sun without adequate protection. The sun emits powerful ultra-violet rays that damage the skin’s surface. The body reacts to this skin damage by redirecting more blood to the burnt area to repair the damage left by the sunburns.You may experience extra tenderness, blisters, skin peeling, and itchiness on the burnt area. Consider investing in high-quality sunscreen to prevent red skin. Other remedies include wearing protective wear, staying under the shade when the sun is too hot and applying sunscreen appropriately.
Your face may be Rosacea’s first target. It manifests itself in the form of redness on the forehead, chin, cheeks, and nose. If left untreated, the skin condition continues to intensify, and blood vessels may become apparent.
In some rare cases, you may notice skin redness on the back, chest, and neck areas. Rosacea may also affect eyes, making them look bloodshot and watery. Individuals with developing Rosacea may also have red solid bumps or pimples filled with pus. Experts recommend medical therapy to manage the signs and symptoms of Rosacea, as there is no known treatment.
3 – Allergic reactions to drugs
- Epilepsy medications.
- Penicillin and some antibiotics.
- Non-steroidal anti-inflammatory drugs such as ibuprofen or aspirin.
If you take medication and begin to see skin rashes, hives, swelling, and skin itching, allergies could explain these reactions. Due to the response of the skin by swelling, itching, and rashes, your skin is bound to become red. Avoid medication that triggers allergic reactions to prevent the occurrence of anaphylaxis.
4 – Cellulitis
It is a potentially severe bacterial skin condition. The infection subjects the skin to appear red and swollen. Most patients complain of pain and warmth in the affected area. Cellulitis appears typically on the lower legs, arms or face.
If left unattended to, the skin will continue to crack open, inviting bacteria to breed on the inflamed area. The bacteria may spread to the bloodstream and lymph nodes which passes the fatal line. Do not ignore skin redness if it tags other severe symptoms such as fever, fatigue, chills, drowsiness, and cold sweats.
5 – Lupus
Lupus isn’t necessarily a skin condition, but it can trigger skin redness. It is a chronic autoimmune condition that forces the immune system to attack specific body organs and tissues. In some cases, the targeted body organ is the skin.
You may notice rashes on the scalp, face, and neck once lupus begins to develop. Normally, the skin redness appears in butterfly shapes that are swollen. The redness, swelling, and inflammation range from mild to severe, depending on the progress of lupus.
6 – Psoriasis
This is yet another chronic autoimmune condition that triggers rapid and unusual production of skin cells. People with psoriasis usually will have a type of scaling accompanied by redness on the skin’s surface. Individuals may also complain of inflammation around the scales.
Psoriatic patches manifest themselves on the skin in whitish-silver colors and gradually develop into thick and layered, red patches. In some cases, the spots may break and begin to bleed. These scales tend to occur on the scalp, elbow, and knees and may appear and disappear in phases. Consult a specialist of the best natural remedies for psoriasis and put the red skin to an end.
7 – Shingles
Also known as Herpes Zoster is a skin condition that homes a dormant chickenpox virus in your nerve tissues. Infected individuals may exhibit localized pain and blistering rash as one of its earliest symptoms. The shingles rash can be painful and itchy, causing skin redness in apparent shades.
The rash typically lasts anywhere between two to four weeks before making a complete recovery. According to experts, shingle rashes are quick to diagnose due to their unique formations and appearance. Shingles only affect people who have had chickenpox in the past.
8 – Heat rash
Heat rash is quite common across all age groups, especially babies. The skin condition occurs when the skin’s sweat glands get blocked and prevent the sweat from being excreted through the pores. The accumulation of sweat in the glands becomes toxic, resulting in a painful rash.
Common signs of a heat rash include red bumps on the skin and itchy or prickly feeling. Due to inflammation and itching effect, the rashes appear as reddened skin accompanied with tiny blisters. Often, heat rashes develop in areas of the skin that fold such as groin and elbow creases.
9 – Dermatitis
According to dermatologists, the term dermatitis is a general word used to refer to skin inflammation. Your skin will appear red, swollen, and dry. Although dermatitis isn’t contagious, the redness on the skin, pain intensity, and dryness vary among people.
There are multiple types of dermatitis in which some are more prevalent among children and others in adults. Some types can last a long time while others just appear and disappear only when triggered. Dermatitis skin conditions are common but can easily be mistaken for other infections. Consider going to an expert for an accurate diagnosis.
10 – Burns
Aside from sunburns that we earlier discussed, there are other ways to contract burns that trigger redness in the skin. They include:
- Radiation burns from exposing the skin to radiation cause redness in the skin. These burns can be a side effect of radiation therapy during cancer treatments or tanning your skin.
- Chemical burns occur after exposing the skin to irritating chemicals such as acids or harsh detergents.
- Thermal burns are arguably one of the most common. They occur when the skin comes into contact with a hot substance such as hot liquids, flames, or steam.
- Friction and electrical burns come about when your skin glazes against rough material or strong electrical current from exposed wires.
Any of these kinds of burns mentioned above can cause red skin in all their forms. Doctors classify burns according to their severity ranging from first-degree, second-degree and third-degree burns come last as the most severe. The pain and redness in a first-degree burn should subside after a few days.
11 – Bites and stings
No one plans to play in the grass and get stung by bees. Insects, wild animals, or birds could inflict bites. Depending on the type of insect or animal that bites or stings you, an irritation from the poison injected into your skin could follow. You will notice swelling, soreness, itching, and redness at the site of the bite or sting.
Even in the absence of toxin in the sting or bite, you will feel some pain in the affected area and adjacent muscles. The redness should be apparent around the sting or bite mark. Consider taking an antihistamine to calm down any allergic reaction triggered by the toxin from the bite or sting.
12 – Scarlet fever rash
Scarlet fever frequently affects kids with strep skin infections and strep throat. The strep bacteria are notoriously known for making a toxin that causes red skin and an abnormally bumpy rash. With time, the rash covers most of the skin.
The scarlet fever rash epitomizes a severe sunburn but with added bumps whose texture feels like sandpaper. The rash may accompany an itch and could go away after about six days in which the skin begins to go back to normal skin color.

Best Ways To Get Rid Of Hives
If you're wondering how to get rid of your hives at home, then we can help. We've created a special Top 10 Best Ways To Get Rid Of Your Hives list that is going to be exactly what you need to determine what is causing your hives and how to stop them quickly and at home with natural remedies.
Are They Contagious?
Hives (AKA urticaria) is not contagious by any means. They are a skin disorder that results in red, sometimes itching patches of raised skin. The patches of skin can be small or large, and generally appear quite fast and disappear on their own within hours or days. They can be as small as a few millimeters and as large as inches, and can even join together to become large areas called plaques. When they join together all over your body, they are generally known as body hives. This form of rash is often quite itchy in nature and can burn. Learn more on our page title "Are Hives Contagious?"
Can Stress Cause Chronic Hives?
Stress hives are also known as a stress rash or as stress bumps. They develop due to chronic stress or tension, and appear as red raised areas and swollen areas on the skin that seem to suddenly appear. They cause itching most of the time, and some people report having a burning or stinging sensation wherever they appear. Learn more about how stress can cause chronic urticaria on our stress rash page.
Your diet might be the cause of your skin rash!
There’s a growing awareness that the food you eat affects every part of your health. If you have a food allergy, you may be prone to skin rashes. Research studies found that your diet can set off eczema. Eczema is a word used to describe a group of skin conditions that cause inflammation, itchiness, red, dry, or bumpiness of your skin.
Most of the time, eczema refers to a condition called atopic dermatitis. If you eat food you’re allergic to your body goes into overdrive. Your immune system’s overreaction releases mast cell chemicals that cause a hypersensitive reaction like histamines.
A reaction can happen minutes or hours after eating the food. Some delayed reactions occur as long as a couple of days later.
Gut and skin connection
A recent study found that scratching your itchy skin irritated by eating foods triggers your immune cells in your small intestine. The scratching sets off a gut reaction. This situation is why there may be varied reactions in people with food allergies. Your food allergy can set off atopic dermatitis or stomach problems or both. You may get a skin rash from foods without a stomach reaction, but some researchers suggest that if you have one result, you are prone to the other response. So, what are common food allergy symptoms? Here is a list you may encounter if you’re allergic to certain foods:
- Itchiness or eczema (atopic dermatitis)
- Tingling around or inside your mouth
- Red skin
- Swelling of your face, lips, tongue or throat-see your doctor right away
- Wheezing, trouble breathing-see your doctor right away
- Dizziness, lightheadedness
- Watery eyes
- Abdominal cramping
Is my rash an allergy?
For instance, one of the most common reactions, a rash, is also one of the most difficult to interpret. Rashes can be caused by food allergies and infections as well, Blumenthal said.
"'Rash' is one of the most common entries in the allergy section of our electronic health records, yet can be entirely nonspecific," Blumenthal told Live Science. For instance, "the typical delayed maculopapular rash that can be commonly caused by drugs is also called a morbilliform rash, which means 'measles-like.'"
Hives, or swollen red bumps and blotches that appear on the skin, (often known as welts) can be a sign of a serious reaction caused by Ig-E.
"Specific rashes are very hard to distinguish and part of our job is to educate all clinicians on how to diagnose the most common and most serious drug reactions. For example, we educate about how to distinguish hives by history and physical exam because hives can lead to a more severe IgE &ndashmediated reaction in the future.
