Can Allergies Cause Lip Blisters

Swollen Lips And Injuries

Even minor trauma that doesn’t break the skin can cause the lips to swell, like sports injuries. It’s also easy to hurt your lips bumping into things or through other minor accidents. The swelling usually goes down without treatment, but sometimes swelling hides other injuries, like cuts and abrasions that can become infected or make chewing and speaking difficult.

What Is A Cold Sore

A cold sore is a group of tiny, painful blisters caused by the herpes simplex virus . Theyâre also called fever blisters or herpes simplex labialis.

Up to 90% of people around the world have at least one form of HSV.

The symptoms are usually the most severe the first you time you get cold sores. A first-time cold sore can make a child seriously ill.

After the first outbreak, your body should make , and you may never have another infection. But many people get cold sores that come back.

Are Lip Blisters Contagious

Unless your blister is caused by a bacterial or viral infection, its NOT contagious to others. Most blisters are caused by an allergic reaction, hot/cold weather or blunt trauma, so the likelihood of a blister posing a health threat to others is relatively small. But there are exceptions to the rule.

What may seem like a blister on the lip thats not a cold sore could actually be a cold sore. They can be the result of undetected diseases and disorders such as Crohns disease, Behçets syndrome, and lupus. If the formation of a blister is accompanied by general sickness symptoms, you should always consult a physician.

Recurrent blisters that give the appearance of a small pimple should be tested for methicillin-resistant Staphylococcus aureus as soon as possible. Rather serious, MRSA is a contagious bacterium that can be contracted through sharing items with an infected individual or having direct contact with the infected person.

The use of public door handles, tables, hand railing, etc. can lead to infection. Very aggressive and resistant to many antibiotics, it is important to get a pus culture done as soon as possible, so proper diagnosis and treatment can begin.

Cancer Cold Sores And Allergies Are Causes

Its hard to ignore a change on your lip, whether its your first glance in the mirror after you wake up or while youre brushing your teeth. Your lips say a lot about your health; if you notice a bump, spot or dot on them it may be a reason to see your doctor. Or, it may be nothing to worry about.

“If youve got a sudden spot on or around your lips there could be a number of causes, some more serious than others,” said Geisinger dermatologist Paul Long, MD.

Heres what it could be:

Cold sore

A cold sore is an infection caused by the herpes simplex virus . These often-painful blisters are typically caused by HSV 1, but can sometimes be caused by HSV 2. About 90 percent of all people get at least one cold sore in their life; many times this happens as a child. Then, they develop antibodies and never experience a second one. Cold sores typically last seven to 10 days, during which the sore forms a blister, the blister breaks and oozes, crusts over and sloughs away.

Cold sores are most contagious when blistering and oozing; however, the virus can be transmitted even when not blistering by sharing a utensil, razor or towel, or by kissing someone. HSV 1 causes most cold sores; however, HSV2, also known as genital herpes, causes a smaller percentage of cold sores.

“Cold sores are typically nothing to worry about, unless your immune system is weakened by a disease,” said Dr. Long.

Skin cancer

If you notice a red or dark sore or bump on your lip, you should see your doctor.

Symptoms Of Blisters On Lips

The first sign that you might have a cold sore is feeling a tingling or burning sensation on your lip before you are even able to see anything. A will then pop up, usually surrounded by red, sensitive skin. It will ooze a clear liquid before drying up and scabbing over.

Other signs and symptoms may vary depending on a variety of factors, like whether or not this is your first time getting a sore. The sores can last from a couple of days to up to two weeks, and they can take two to three weeks to heal completely. Recurrences are likely to appear in the same spot on the lips, but they tend to be less severe than the first outbreak.

Other symptoms that may occur during an initial outbreak include:

Key Points About Mouth Sores And Inflammation

  • A mouth sore that lasts more than 10 days should be evaluated by a doctor or dentist.

  • Isolated mouth sores in people with no other symptoms or risk factors for a systemic illness are usually caused by a viral infection or recurrent aphthous stomatitis.

  • Symptoms outside the mouth, a rash, or both suggest a more immediate need for evaluation.

Questions For Diagnosing The Cause Of Lip Swelling

To help diagnose the underlying cause of lip swelling, your licensed health care practitioner will ask you several questions related to your symptoms. Questions asked during your examination generally include:

  • When did the lip swelling start?
  • How long has the lip swelling lasted? Does it come and go?
  • Did you eat any foods or have contact with any unusual substances before the swelling started ?
  • Have you had any recent infections or injuries to the mouth or lips?
  • Do you have any or other symptoms?

How Can You Prevent Allergic Reactions

The best way to prevent allergic reactions, treatment-related or otherwise, is to identify the cause. While unfortunate, many times it takes a reaction to serve as future avoidance prevention.

Because a potential list of things can cause a reaction, it is important to know your situation. Are you naturally allergic to certain medications? Certain foods? Certain chemicals/ingredients? When it comes to allergies, knowledge is often the best form of prevention. Making notes, quite literally, can often save you from a negative experience in the future.

Most everything can be traced back to understanding HSV-1 and cold sore symptoms. While you might not be able to understand everything fully, you can tell if the problematic blemish is a cold sore or not.

To Summarize:

  • Remembering your bad experiences with specific products, for example, can serve as future prevention. You will only touch a hot stove once. This logic/motto can be applied to various things that have caused you to have a negative reaction in the past.
  • Prevention can be two-fold. It is important to remember that allergic reactions can cause cold sores. While attention has been paid to reaction-causing blisters that are unrelated to HSV-1, reactions can trigger fever blisters. Through acts of prevention, you can kill two birds with one stone. You can quell cold sores as well as other types of blisters caused by outside influences such as food, drink, medication, etc.

Common Causes Of A Sore Throat With Blisters Or Ulcers

If youve ever had a cold, strep throat, or even allergies, youve probably experienced the discomfort of a sore throat. Sore throats are a pain for everyone, and when you have strep throat blisters, ulcers, or other sores in your throat, your discomfort level can go from bad to worse in an instant. Because a variety of viruses and conditions can cause a sore throat or sores on the back of your throat, its important to be aware of what to do when you find yourself with telling symptoms.

How To Treat An Allergic Reaction To Cold Sore Medication

If you are experiencing an allergic reaction due to cold sore medication, it is imperative that you consult your physician. Attempting to treat a reaction without a proper diagnosis could make the situation much worse.

Additionally, when consulting your physician, it is essential that you bring your OTC treatment with you. The ability to show your doctor which medication you are taking can be helpful. This will allow the specific issue to be identified and hopefully treated in a timely fashion.

Once the adverse reaction has been remedied, your physician will also be able to put you on the right path towards faster cold sore healing. Although rare, some OTC treatments can cause a reaction. It is logical to conclude that some people would have no previous knowledge of any existing allergy before having a cold sore outbreak. This is because cold sore treatments are likely not used for other means.

    In the cases of minor infections, like thrush and oral herpes, a doctor can often make a diagnosis solely through a visual examination.

    Is It A Cold Sore Or A Canker Sore

    Cold sores are a cluster of blisters that first appear clear then become cloudy. First infection may be inside the mouth, but cold sores generally appear outside the mouth on the lips.

    Canker sores are gray or white sores surrounded by a red inflamed area. They occur only inside the mouth, on the tongue or the insides of the cheeks, lips or throat.

    Who Gets Allergic Contact Cheilitis And Why

    Allergic contact cheilitis is a common cause of lip inflammation and is more common than contact stomatitis, despite considerable overlap in allergen sources. Approximately one quarter of cases of chroniceczematous cheilitis are due to allergic contact. The rest are due to constitutional and irritant factors.

    Allergic contact cheilitis is more common in women than men. It can affect all age groups, but adults are more commonly affected than children. However the allergens involved vary in different age groups. These differences reflect the usage patterns of the different age groups and sexes.

    • Lip cosmetics are the most common allergen source in women, and toothpastes in men.
    • Medications are an important source of allergic contact cheilitis reactions in the elderly.
    • Dental materials and oral hygiene products cause cheilitis in all age groups.
    • Reactions to food mainly affect children.
    • Patients are often also .

    Food Allergies Vs Sensitivities

    There is a difference between the two conditions thought they are often used interchangeably. A food allergy is bodys immune reaction against some specific proteins found in certain foods. The symptoms that may develop within minutes of even the tiniest consumption of the specific food or ingredient have the potential to cause life-threatening reaction . Most commonly seen food allergies are to  eggs, milk, peanuts, shellfish or other seafood, soy, tree nuts, and wheat. These account for 90% of the food allergies in the various populations of the world.

    On the contrary, food intolerance or sensitivity is rarely a risk for life and has no association with your immune system but instead with your digestive system. It manifests after consumption of larger amounts of food that is not friendly to your digestive apparatus. Most commonly, it is milk and milk products or gluten containing products to which the body shows intolerance.

    Once you have determined what causes your canker sores, you can work on eliminating the trigger and hopefully minimize or even get rid of outbreaks. In the meantime on this site you will find a  variety of treatments you can try at home to help soothe your sores.

    Food Sensitivity Or Allergy

    Thats right certain foods may make your tongue hurt. You may have whats called oral allergy syndrome. This condition is also known as pollen-food syndrome, and its most often caused by raw fruits, vegetables, and certain tree nuts.

    Along with a sore tongue, you might experience:

    • an itchy mouth
    • a scratchy throat
    • swelling of your lips, mouth, or tongue

    Oral allergy syndrome is more likely to start in older children, teens, and younger adults. If your reaction is severe, your doctor may suggest you carry an epinephrine auto-injector.

    Smoking and even stopping smoking can cause tongue pain. When you smoke, you also put yourself at a higher risk of developing cancer in your and .

    Other issues smoking can cause in your mouth include:

    • stained teeth
    • muscle weakness
    • numbness or tingling in your hands and feet

    Vitamin deficiencies generally develop over a long period of time anywhere from several months to years. Treatment involves eating a well-balanced diet, taking supplements, and sometimes receiving vitamin injections.

    Preventions And Treatments For Tomato Allergy

    Allergies are mistaken by your body as being harmful; therefore, your immune system will release antibodies to counteract the harmful ingredient. The next time you eat that food, your immune system delivers histamine along with other chemicals into the bloodstream, causing a wide arrange of symptoms such as runny nose, itchy eyes, rashes and hives, nausea, diarrhea, breathing difficulties or anaphylactic shock.

    1. Preventions

    There are several ways you can verify and prevent tomato allergic reactions.

    Avoid eating tomatoes or having any contact with them if you are diagnosed with tomato allergy. Here are some tomatoes and tomato products to avoid:

    • Fresh  tomato: Avoid eating raw tomato in all forms, such as tomato in salsa or natural dried tomato. 
    • Cooked tomato: Some may be allergic to fresh tomatoes, while others can get symptoms when eating cooked tomatoes, including pureed tomato, pasta sauces, chili, etc.
    • Nightshade vegetables: You may need to consult a doctor to confirm whether you can eat vegetables in nightshade family, such as bell peppers, eggplant. Because tomato is one kind of nightshade family vegetables and the other vegetables in the same family contain similar proteins, which may also cause tomato allergy symptoms. 

    Always check the labels on food products for anything that might contain tomatoes and be aware of the places where others food may be polluted by tomatoes, as well as ask if theres any ingredient of tomato when youre dining in a restaurant.

    • Foods That Cause Mouth Ulcers

    Mouth ulcers are common and mostly harmless sores that occur inside the mouth. However, anyone whos had one knows how unpleasant they are.

    There are many things that cause these painful sores. Anxiety, stress, biting the inside of your cheek, and smoking are some typical reasons why you develop canker sores. What you eat is a huge contributor as well.

Its important to visit a that knows how to identify the source of your canker sore problem and offer fast treatment. This way, you can get some professional advice that is also personalized to you.

    In the meantime, read on to find out what major foods can cause mouth ulcers.

    What Can You Do To Prevent Mouth Ulcers

    Painful mouth sores

    Many people with food allergies or sensitivities tend to get a burning or tingly sensation prior to the canker sore developing, which is a signal they have eaten something to which they are sensitive. If you suspect your canker sores are caused by a food allergy, try an elimination diet to pin down the offending food or foods. Now that you know the most common allergens, this should not be too difficult to figure out. However, it is by no mean an exhaustive list, as they could be many other possible offenders, depending on the individual. Most people find that once they remove the problematic food or foods from their diet, their canker sore outbreaks lessen or disappear.

    Causes Of Blisters On Lips

    simplex virus is the main culprit for this contagious viral infection. The infection spreads when an individual involves in kissing with the infected person and also by sharing food and utensils with them. There are two major types of herpes simplex virus which are known as type 1 or type 2. Type 1 is responsible for oral herpes called blisters. Type 2 causes genital herpes.

    Once you have the herpes simplex virus, you are caught with it as there is no cure. The herpes simplex virus becomes inactive in your system until to certain degree something triggers it such as stress or illness.

    One advantage is that you will typically get a notice before an outbreak. Many times you will get a tingling, burning or aching sensation in the area where the blister will break out a day or two before it occurs.

    Is It Cold Sores Or An Allergic Reaction

    While an allergic reaction can undoubtedly trigger a cold sore, it can also cause other types of blisters. This is why it is so vital to have a basic knowledge of HSV-1 and the symptoms. Not all lip blisters, even for those who carry HSV-1, are cold sores.

    Many internal and external elements can trigger a reaction. Some of these elements include the following:

    • Foods
    • Intense weather conditions
    • Existing allergies

    Depending on your unique medical history, allergic reactions are possible. This is especially true if you have a known history and actively attempt to steer clear of specific triggers.

    If you have allergies in addition to HSV-1 the water can get a bit muddied.

    To recap:

    • Not every lip blister is a cold sore. This even holds true for those who have HSV-1 and have had many cold sore outbreaks. It is entirely possible that your painful blister is related to an allergic reaction.
    • There are several known interactions, both internal and external, that can irritate your lips and mouth. Something as basic as lip balm, for example, could cause lip blisters and irritation if you develop an allergic reaction to its ingredients.
    • Understanding the symptoms of a cold sore can never be understated. This can allow you to define or eliminate the cause of your blisters based on how they have formed and their progress. Knowing the difference between a cold sore and a chemical reaction, for example, can allow you to know what steps need to be taken.

    How Do You Get A Canker Sore After Exposure To A Allergen Source

    Your immune system regards the food substance as foreign material which can be dangerous for your body and triggers a series of reactions to form immune cells against them,  which release histamine. This  can cause the clinical symptoms of inflammation, irritation and itching. However, in your fragile and sensitive oral cavity there can be direct cellular or tissue damage leading to the break-up of the intact skin which allows the oral ulcers to appear. The pain associated is due to the exposed free nerve endings of the skin which get damaged by slightest of physical or chemical insult.

    Swelling Caused By Use Of An Ace Inhibitor

    ACE Inhibitors are drugs used to prevent, treat or improve symptoms in conditions such as high blood pressure, coronary artery disease, heart failure and diabetes. In rare cases, these drugs can cause an allergic reaction that can be life-threatening.

    Rarity: Common

    Top Symptoms: shortness of breath, swollen face, trouble swallowing, swollen lips, swollen tongue

    Symptoms that never occur with swelling caused by use of an ace inhibitor: hives, red swollen bumps or patches with a pale center

    Urgency: Hospital emergency room

    When To Get Medical Advice

    See your GP if you have episodes of swelling that affect your skin or lips and you’re not certain of the cause.

    You may need to have some tests to determine the cause. Read more about tests for angioedema.

    Dial 999 for an ambulance if you, or someone with you, has swelling and:

    • sudden or worsening breathing problems 
    • feels faint or dizzy
    • passes out or collapses 

    These are signs of a serious allergic reaction . If you, or the person who’s ill, have been prescribed an adrenaline auto-injector for this, use it while waiting for the ambulance to arrive.
