10 Possible Rash With Bumps Or Blisters Causes

The list below shows results from the use of our quiz by Buoy users who experienced rash with bumps or blisters. This list does not constitute medical advice and may not accurately represent what you have.

Skin abscess

A skin abscess is a large pocket of pus that has formed just beneath the skin. It is caused by bacteria getting under the skin, usually through a small cut or scratch, and beginning to multiply. The body fights the invasion with white blood cells, which kill some of the infected tissue but form pus within the cavity that remains.

Symptoms include a large, red, swollen, painful lump of pus anywhere on the body beneath the skin. There may be fever, chills, and body aches from the infection.

If not treated, there is the risk of an abscess enlarging, spreading, and causing serious illness.

Diagnosis is made through physical examination.

A small abscess may heal on its own, through the body's immune system. But some will need to be drained or lanced in a medical provider's office so that the pus can be cleaned out. Antibiotics are usually prescribed.

Keeping the skin clean, and using only clean clothes and towels, will help to make sure that the abscess does not recur.

Rarity: Common

Top Symptoms: rash with bumps or blisters, red rash, red skin bump larger than 1/2 cm in diameter, pus-filled rash, rash

Symptoms that always occur with skin abscess: rash with bumps or blisters

Urgency: Primary care doctor

Non-specific dermatitis (skin inflammation)

Nonspecific dermatitis, or contact dermatitis, simply means inflammation of the skin from many different causes.

Most nonspecific dermatitis is caused by skin contact with a substance that provokes a reaction, which could be anything from plants to soap to jewelry to fabrics. Some may be due to an autoimmune condition, where the body's immune system attacks itself.

Risk factors include a family or personal history of allergies, asthma, or other condition which weakens the immune system; or constant contact with metals, plant life, or chemicals.

Symptoms commonly include red, swollen skin rash with itching, blistering, or oozing, which may become painful and infected.

Dermatitis itself is not contagious but can interfere with quality of life. A medical provider can help with managing the symptoms.

Diagnosis is made through patient history, physical examination, and sometimes skin biopsy and patch testing.

Treatment involves using protective measures if the substances cannot be avoided; making nutritional improvements to strengthen the immune system; using corticosteroid or other creams; and phototherapy.

Rarity: Common

Top Symptoms: red rash, itchy rash, painful rash

Symptoms that always occur with non-specific dermatitis (skin inflammation): red rash

Urgency: Self-treatment

Non-specific skin rash

Common causes of rash are contact dermatitis, sun damage, or allergic reaction. However, many rashes are a symptom of disease and should not be ignored.

Nonspecific rashes have widely varied symptoms:

  • May be flat and smooth; slightly raised or with swollen welts; clean and dry; or blistered and oozing.

May spread widely over the body, or be confined to one site.

  • May appear after eating certain foods; or after exposure to certain plants or to insect stings or bites.

Other symptoms may be present, including pain anywhere in the body; nausea; vomiting; fever; headache; or abdominal pain and upset.

Diagnosis is made through patient history and physical examination to determine the exact type, location, and history of the rash, along with any other symptoms that may be present.

Those symptoms will be investigated with blood tests or imaging. Skin swabs may be taken and tested. After the process has ruled out as many causes as possible, a course of treatment can be determined.

Rarity: Common

Top Symptoms: rash

Symptoms that always occur with non-specific skin rash: rash

Urgency: Wait and watch

Eczema (atopic dermatitis)

Eczema (atopic dermatitis) is a non-contagious chronic skin condition that produces an itchy rash. It is caused by a genetic condition that affects the skin's ability to protect itself from bacteria and allergens. The most susceptible are those with a family history of atopic dermatitis, asthma, or hay fever.

Infants will have a dry, scaly, itchy rash on the scalp, forehead, and cheeks. Older children will have the rash in the creases of elbows, knees, and buttocks.

Without treatment, a child may have trouble sleeping due to the intense itching. Constant scratching may cause skin infections.

Eczema cannot be cured, but it can be controlled through prescribed medications, skin care, stress management, and treatment of food allergies. People with eczema often have allergies to milk, nuts, and shellfish. Keeping the skin clean and moisturized helps prevent flares.

Rarity: Common

Top Symptoms: trouble sleeping, feeling itchy or tingling all over, dry skin, scalp itchiness, flexor surface rash

Symptoms that never occur with eczema (atopic dermatitis): fever

Urgency: Phone call or in-person visit

Benign skin growth

Benign skin growths are very common and virtually everyone has some form of them. "Benign" means the growth is not cancerous and not harmful. Some of these growths have genetic origins, and for some the cause is not clear.

Common types are:

  • Birthmarks – may appear as flat "stains" in the skin or as raised clusters formed of tiny blood vessels.
  • Moles – small irregularities that originate in the pigment-producing cells in the skin. They can be almost any shape or color but are normally no larger than one-quarter of an inch across.
  • Skin tags – little irregular flaps of skin, like a flattened mole attached on only one side.
  • Keloids – a dark, fibrous form of scar tissue that forms after a skin wound, either from trauma or from surgery.

As a person ages, more changes may appear in the skin. Most are benign, but any unusual or suspicious skin growth should be checked by a medical provider. The growth can be removed if it is unsightly, interferes with clothing, or proves to be malignant (cancerous.)

Rarity: Common

Top Symptoms: constant skin changes, itchy rash, rash with well-defined border, abdominal skin changes, neck skin changes

Symptoms that always occur with benign skin growth: constant skin changes

Symptoms that never occur with benign skin growth: cherry red lower leg bump

Urgency: Wait and watch

Irritant contact dermatitis

Irritant contact dermatitis means a skin reaction that is caused by directly touching an irritating substance, and not by an infectious agent such as a bacteria or virus.

Common causes are soap, bleach, cleaning agents, chemicals, and even water. Almost any substance can cause it with prolonged exposure. Contact dermatitis is not contagious.

Anyone who works with an irritating substance can contract the condition. Mechanics, beauticians, housekeepers, restaurant workers, and health care providers are all susceptible.

Symptoms include skin that feels swollen, stiff, and dry, and becomes cracked and blistered with painful open sores.

A medical provider can give the best advice on how to heal the skin and avoid further irritation. Self-treatment can make the problem worse if the wrong creams or ointments are used.

Diagnosis is made through patient history, to find out what substances the patient comes into contact with, and through physical examination of the damaged skin.

Treatment involves avoiding the irritating substance if possible. Otherwise, the person can use petroleum jelly on the hands underneath cotton and then rubber gloves.

Rarity: Common

Top Symptoms: rash with well-defined border, itchy rash, red or pink, rough patch of skin, painful rash, red rash

Symptoms that always occur with irritant contact dermatitis: rash with well-defined border

Symptoms that never occur with irritant contact dermatitis: fever, black-colored skin changes, brown-colored skin changes, blue-colored skin changes

Urgency: Self-treatment

Hives

Hives, or urticaria, are flat red welts that can appear anywhere on the skin and usually itch. Hives often occur as an allergic reaction to something eaten or something that has contacted the skin. Foods, medicines, and plants are common causes, but sun exposure, stress, infections, and autoimmune diseases have also been known to cause hives.

Symptoms include an itchy, stinging pink rash of slightly swollen skin. The rash may wax and wane in severity. Acute hives typically resolve within six weeks, but chronic hives can persist for months or years.

Hives often resolve on their own, especially in children. Otherwise, treatment for acute hives involves oral antihistamine medications to help relieve the itching and stinging. Chronic hives that do not improve with antihistamines may be treated additionally with corticosteroids, antibiotics, and other stronger medicines.

Rarity: Common

Top Symptoms: red or pink, rough patch of skin, itchy rash, curved rash, insect bite or sting, hives, red swollen bumps or patches with a pale center

Symptoms that always occur with hives: red or pink, rough patch of skin

Urgency: Self-treatment

Molluscum contagiosum

Molluscum contagiosum, also called "water warts," is a common, benign, viral skin infection. It causes a rash of bumps that may appear anywhere on the body.

The virus spreads through direct contact with the bumps, including sexual contact. It also spreads through touching any object that an infected person has handled, such as clothing, towels, and toys.

Most susceptible are children under age 10. Other risk factors include dermatitis causing breaks in the skin; a weakened immune system; and living in warm, humid regions under crowded conditions.

Symptoms include a rash of small, pale bumps with a pit in the center. The rash is usually painless but may become reddened, itchy, and sore.

Diagnosis is made through physical examination.

In some cases, treatment is not needed and the condition will clear on its own. However, if the bumps are unsightly or are present in the genital area, lesions can be removed through minor surgical procedures or treated with oral medication or topical agents.

Rarity: Common

Top Symptoms: rash with bumps or blisters, leg skin changes, skin changes on arm, head or neck skin changes, genital skin changes

Symptoms that never occur with molluscum contagiosum: fever, headache

Urgency: Phone call or in-person visit

Seborrheic dermatitis

Seborrheic dermatitis is a common chronic inflammatory skin condition that causes flaky, white to yellowish scales to form on oily areas such as the scalp, face or inside the ear. It can occur with or without reddened skin. The exact cause of this condition is not known, although doctors think that some common skin yeast organisms, called Malassezia, may play a role in some people.

Rarity: Common

Top Symptoms: itchy rash, red or pink, rough patch of skin, rash with well-defined border, scalp skin changes, cheek skin changes

Symptoms that never occur with seborrheic dermatitis: fever

Urgency: Phone call or in-person visit

Boil (furuncle)

A furuncle, also called a boil, is infection of a hair follicle. The infection forms under the skin at the root of the hair and may occur anywhere on the body.

The infection is caused by bacteria, most often Staphylococcus aureus or "staph." Irritation caused by clothes or anything else rubbing the skin can cause the skin to break down and allow bacteria to enter.

Staph bacteria are found everywhere. Frequent and thorough handwashing, and otherwise maintaining cleanliness, will help to prevent its spread.

Most susceptible are those with a weakened immune system; diabetes; and other skin infections.

Symptoms include a single bump under the skin that is swollen, painful, and red, and contains pus.

It is important to treat the boil, since infection can spread into the bloodstream and travel throughout the body.

Diagnosis is made through physical examination and sometimes fluid sample from the boil.

Treatment may involve incision and drainage of the infection, followed by creams to apply to the site of the boil and/or a course of antibiotic medicine.

Rarity: Uncommon

Top Symptoms: pink or red facial bump, small facial lump, painful facial bump, marble sized facial lump, constant skin changes

Symptoms that always occur with boil (furuncle): pink or red facial bump

Symptoms that never occur with boil (furuncle): fever

Urgency: Self-treatment
