Causes, Symptoms and Treatment Options. What Is It? A blister is a bubble of fluid under the skin. The clear, watery liquid inside a blister is called serum.
- Blisters are small raised areas that are filled with fluid and located in the superficial layer of the skin. They look like bubbles on the surface of the skin.
- Rash on face blisters. The rash develops into small, fluid-filled blisters.
- Canker sores (also called aphthous ulcers) are different than fever blisters.
It leaks in from neighboring tissues as a reaction to injured skin. If the blister remains unopened, serum can provide natural protection for the skin beneath it. Small blisters are called vesicles. Those larger than half an inch are called bullae. A blood blister is filled with blood, rather than serum. There are many causes of blisters, including: Irritation .

Blisters can result from an ill. Pictures of Blisters: Causes and. Never ignore professional medical advice in seeking treatment because of something you have. I have patches of inflamed spots/blisters on my face that move around but will not disappear. It started last September during a summer holiday with a patch of small.
Blisters on the feet can result from shoes that are either too tight or rub the skin in one particular area. Blisters also can be caused by contact dermatitis, a skin reaction to some type of chemical irritant. Intense cold can trigger frostbite, which often leads to blisters once the skin is rewarmed. Any type of burn, even sunburn, also can cause blisters. Allergic contact dermatitis is caused by an allergy to a chemical or poison, such as poison ivy, poison oak or poison sumac.
Examples include dermatitis herpetiformis, pemphigoid and pemphigus. There also are inherited forms of blistering skin conditions, such as epidermolysis bullosa (in which pressure or trauma commonly leads to blisters) and porphyria cutanea tarda (in which sun exposure provokes blisters). Others, such as the doxycycline (Vibramycin), can increase the risk of blistering sunburn by increasing the skin's sensitivity to sunlight.

In more dramatic cases, medications can trigger more severe, even life- threatening, blistering disorders, such as erythema multiforme or toxic epidermal necrolysis, also known as TEN, an illness that causes severe skin damage and typically involves 3. Symptoms. In general, blisters are round or oval bubbles of fluid under the skin that may be painful or itchy, or they may not cause any symptoms. Symptoms vary depending on the cause. Irritation, burns and allergies . Blisters resulting from eczema can be accompanied by redness, severe itching and small bumps on the affected skin.
Infections . Examples include: Bullous impetigo . Herpes simplex virus .
They typically appear on the lips. The affected skin may itch, tingle, swell and become red before the blisters appear. When the blisters eventually break, they leak fluid, and then painful sores develop.
Herpes simplex type 2 is the most common cause of genital herpes, a sexually transmitted infection (although type 1 also can cause genital herpes). Generally, small red bumps appear before blisters develop in the affected area, typically the vaginal area or penis, the buttocks and thighs, or the anus. Other symptoms can include fever, muscle aches, headache and burning with urination. Varicella zoster virus . Varicella zoster also can cause shingles (herpes zoster). People with shingles may experience small, painful blisters that usually erupt in a linear pattern along the length of an infected nerve. Other symptoms include fever, sore throat, cough and muscle pain.
The autoimmune diseases (also known as bullous diseases because of the large blisters seen) vary in appearance as well. Dermatitis herpetiformis causes itchy, red bumps or blisters. Pemphigoid, an uncommon condition that primarily affects the elderly, results in large, itchy blisters, and pemphigus, an uncommon disease that tends to strike in middle age, causes blisters inside the mouth and on the surface of the skin. The blisters of pemphigus break easily and leave painful areas. In some cases, there is only an increased sensitivity to the sun, which can lead to blistering sunburn if the skin is exposed to the sun.
In more severe reactions, such as TEN, blisters can involve larger areas of tissue, including parts of the respiratory passages and gastrointestinal tract, accompanied by fever and malaise (a generally sick feeling). Diagnosis. If the cause of your blisters is not obvious, your doctor will ask about your family history and your personal medical history, including any allergies you have and any medications you take, including over- the- counter medications. You also will be asked about any recent exposure to irritating chemicals or allergens. Your doctor often can diagnose the cause of your blisters by their appearance and your history.
If your doctor suspects an allergic reaction, he or she may recommend patch tests with chemicals to identify the allergen. Some blistering diseases are diagnosed with a skin biopsy, in which a small piece of tissue is removed and examined in a laboratory. Expected Duration. How long blisters last depends on their cause. For example, blisters caused by irritation generally go away on their own within a few days, and those triggered by infections and skin diseases can remain for weeks or months. With an autoimmune blistering disorder, blistering may be chronic (long- lasting) and requires ongoing treatment. In skin infections, such as herpes simplex virus infection, the blisters can come back periodically.
Blistering skin diseases that result from inherited causes also are long- lasting. Prevention. There are many simple strategies to prevent blisters caused by skin irritation. You can wear comfortable shoes that fit well, with socks that cushion the feet and absorb sweat. Apply sunscreen to protect your skin from sunburn.
Be particularly vigilant about avoiding sun exposure if you are taking medications that are known to cause sun sensitivity, such as doxycycline (sold under many brand names). During cold months, use mittens, hats and heavy socks to protect your skin against freezing temperatures and chilling winds. As much as possible, avoid irritants and allergens that tend to trigger eczema, such as certain hygiene products (bubble baths, feminine hygiene sprays, detergents), certain metals in jewelry, especially nickel, and irritating plants such as poison ivy. To prevent blisters caused by infections, wash your hands often and never touch skin sores, cuts or any open or broken areas of skin on other people. To reduce the risk of herpes simplex, never have sex (even with a condom) with someone with active herpes. In addition, the fewer sexual partners you have, the lower your risk of herpes simplex. To avoid the spread of childhood infections, try to prevent children from sharing toys and utensils that have touched another child's mouth.
To prevent chickenpox and to help prevent shingles later, have your child immunized with the varicella vaccine. People who have not had chickenpox should avoid people with chickenpox or shingles until all of the blisters have crusted over. Adults can be vaccinated if they have never had chickenpox, especially if they are at risk of exposure (for example, day- care workers and teachers). There is no known way to prevent many of the blistering diseases such as the hereditary forms and the autoimmune (bullous) diseases. Treatment. Usually, it is best to leave blisters alone. Because blisters protect the underlying skin, breaking blisters open can increase the chance of infection. Protect blisters with a bandage and cover them until they heal on their own.
The liquid in the blister will be re- absorbed and the skin will flatten naturally. If a blister breaks, wash the area with soap and water, then apply a bandage. If a blister is very large or painful, your doctor may drain it and apply an antibacterial cream to prevent infection. The treatment for blisters caused by eczema, infections and other diseases varies. Some cases of eczema can be treated with corticosteroid cream or pills. Herpes simplex infections and shingles (herpes zoster) sometimes are treated with antiviral medications.
Antibiotic cream or pills may be given for impetigo. Chickenpox and coxsackievirus generally are left to go away on their own.
The itching caused by chickenpox can be relieved with over- the- counter anti- itch lotions, such as calamine. With medication- related erythema multiforme, the medication must be discontinued immediately. Corticosteroids sometimes may be prescribed. Pemphigoid and pemphigus are treated with corticosteroids and/or other immunosuppressive agents. Because dermatitis herpetiformis is associated with celiac sprue (a condition that develops as an immune reaction to gluten in the diet), people with dermatitis herpetiformis may benefit from a diet that does not contain any gluten (a substance found in most grains).
Porphyria can be treated with regular removal of blood (phlebotomy) or with medications, including hydroxychloroquine or chloroquine. Also call your doctor if a blister develops signs of infection, such as increasing redness, red streaks in nearby skin, oozing blood or pus, increased pain or swelling of the surrounding skin. Prognosis. In many cases, blisters will disappear when the cause is removed or the infection has gone away, usually in a matter of days or weeks. In most herpes infections, blisters can return in the same spot (such as fever blisters on the lips or genital herpes) weeks, months or even years after the first blisters appear. Pemphigoid and pemphigus are typically chronic (long- lasting) and require long- term therapy. External resources.

Two of the most common recurrent oral lesions are fever blisters (also known as cold sores) and canker sores. Though similar, fever blisters and canker sores have important differences. What are fever blisters?
Fever blisters are fluid- filled blisters that commonly occur on the lips. They also can occur on the gums and roof of the mouth (hard palate), but this is rare. Fever blisters are usually painful; pain may precede the appearance of the lesion by a few days. The blisters rupture within hours, then crust over. They last about seven to ten days. Why do fever blisters reoccur?
Fever blisters result from a herpes simplex virus that becomes active. This virus is latent (dormant) in afflicted people, but can be activated by conditions such as stress, fever, trauma, hormonal changes, and exposure to sunlight. When lesions reappear, they tend to form in the same location. Are fever blisters contagious? Yes, the time from blister rupture until the sore is completely healed is the time of greatest risk for spread of infection. The virus can spread to the afflicted person. While there is no cure now, scientists are trying to develop one, so hopefully fever blisters will be a curable disorder in the future.
Tips to prevent spreading fever blisters? Canker sores (also called aphthous ulcers) are different than fever blisters. They are small, red or white, shallow ulcers occurring on the tongue, soft palate, or inside the lips and cheeks; they do not occur in the roof of the mouth or the gums. They are quite painful, and usually last 5- 1. Who is most likely to get canker sores, and what causes them? Eighty percent of the U. S. The best available evidence suggests that canker sores result from an altered local immune response associated with stress, trauma, or irritation.
Acidic foods (e. g., tomatoes, citrus fruits, and some nuts) are known to cause irritation in some patients. Are canker sores contagious? How are they treated? Because they are not caused by bacteria or viral agents, they are not contagious and cannot be spread locally or to anyone else. Treatment is directed toward relieving discomfort and guarding against infection. A topical corticosteroid preparation such as triamcinolone dental paste (Kenalog in Orabase 0.
When should a physician be consulted? Consider consulting a physician if a mouth sore has not healed within two weeks. Mouth sores offer an easy way for germs and viruses to get into the body, so it is easy for infections to develop. People who consume alcohol, smokers, smokeless tobacco users, chemotherapy or radiation patients, bone marrow or stem cell recipients, or patients with weak immune systems should also consider having regular oral screenings by a physician.
The first sign of oral cancer is a mouth sore that does not heal. What kind of screenings are performed? The physician will most likely examine the head, face, neck, lips, gums, and high- risk areas inside the mouth, such as the floor of the mouth, the area under the tongue, the front and sides of the tongue, and the roof of the mouth or soft palate. If a suspicious lesion is found, the physician may recommend collecting and testing soft tissue from the oral cavity.
What are other types of oral lesions to be concerned about? Leukoplakia. These patches are caused by excess cell growth and are common among tobacco users. They can result from irritations such as ill- fitting dentures or the habit of chewing on the inside of the cheek. Leukoplakia can progress to cancer.
Candidiasis. It is common among denture wearers and most often occurs in people who are very young, elderly, debilitated by disease, or who have a problem with their immune system. People who have dry mouth syndrome are very susceptible to candidiasis.
Candida may flourish after antibiotic treatment, which can decrease normal bacteria in the mouth. Hairy tongue . It can be caused by poor oral hygiene, chronic oral irritation, or smoking. Torus palatinus .
It commonly occurs in females over the age of 3. A torus palatinus is often seen in patients who suffer from tooth grinding. Occasionally it is removed for the proper fitting of dentures. Oral cancer . Other than the lips, the most common areas for oral cancer to develop are on the tongue and the floor of the mouth. Other symptoms include a lump or mass that can be felt inside the mouth or neck; pain or difficulty in swallowing, speaking, or chewing; any wart- like mass; hoarseness that lasts for more than two weeks; or any numbness in the oral/facial region.
