10 Possible Bright Red Skin Bump Causes

The list below shows results from the use of our quiz by Buoy users who experienced bright red skin bump. This list does not constitute medical advice and may not accurately represent what you have.

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

Chronic hepatitis c

Chronic hepatitis C is a liver inflammation caused by Hepacivirus C.

If someone is infected with hepatitis C and gets the acute form of the disease, there is about a 50% chance of the disease becoming chronic. This means that the virus remains in the body after the acute, short-term disease is over, and may or may not cause further illness.

Some patients have no symptoms of chronic hepatitis C until years later, when liver damage has developed and the signs of cirrhosis (scarring) begin to appear. Hepatitis C can also lead to liver cancer.

Diagnosis is made through blood tests.

Treatment for chronic hepatitis C involves taking medications prescribed by the physician; avoiding alcohol; and using no supplements or prescription medications without a doctor's clearance. In some cases, a liver transplant will be needed to save the patient's life.

The best prevention is to never share needles, toothbrushes, or other personal care items, and to always practice safe sex. There is no vaccine for hepatitis C.

Rarity: Common

Top Symptoms: fatigue, nausea, muscle aches, loss of appetite, joint pain

Symptoms that never occur with chronic hepatitis c: pain in the lower right abdomen, pain in the lower left abdomen, pain in the upper left abdomen, pain around the belly button

Urgency: Primary care doctor

Pityriasis rosea

Pityriasis rosea is a common skin rash and is thought to be due to a type of herpes virus. It is not contagious and is not sexually transmitted. Most susceptible are teenagers and young adults.

Symptoms include a single large scaly patch somewhere on the body. In the next 7 to 14 days similar oval pink patches on the arms, legs, and trunk appear, sometimes in a pattern of lines.

There may also be itching, fatigue, and body aches along with the rash. Anything that raises body temperature, such as exercising or a hot bath, may worsen the rash.

The condition may last for a few weeks and is normally gone after three to four months. Sometimes flat brown spots are left as the rash fades.

Pityriasis rosea can resemble other conditions, so getting an accurate diagnosis is important. Diagnosis is made through blood tests and skin cultures.

Treatment involves topical medications for itching, as well as antiviral and anti-inflammatory medications by mouth to aid healing. Cool baths and reduced exercise will also help.

Rarity: Rare

Top Symptoms: rash, itchy rash, curved rash, rough patch with red spots around it

Symptoms that always occur with pityriasis rosea: rash

Symptoms that never occur with pityriasis rosea: blue-colored skin changes, black-colored skin changes, brown-colored skin changes

Urgency: Self-treatment

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 hi...

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

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

Keratoacanthoma (a common, benign skin change)

Keratoacanthomas are rapidly growing lesions that occur primarily on sun-exposed skin in older persons. The majority of lesions involve the face and upper extremities, although they frequently occur on the lower extremities, especially in women.

Rarity: Uncommon

Top Symptoms: itchy rash, rash on sun-exposed areas, red skin bump larger than 1/2 cm in diameter, skin-colored rash, skin-colored, large (>1/2 cm) bump

Symptoms that never occur with keratoacanthoma (a common, benign skin change): fever

Urgency: Wait and watch

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

Churg-strauss syndrome

Churg-Strauss syndrome (CSS) is an extremely rare disease which involves inflammation in certain types of cells in the blood or in tissues. This inflammation causes injury to many organ systems, and the cause of CSS is not known well by doctors.

Rarity: Ultra rare

Top Symptoms: fatigue, abdominal pain (stomach ache), muscle aches, shortness of breath, cough

Urgency: Primary care doctor

Cherry angioma

Cherry angiomas are small, red, harmless skin findings that occur commonly in older adults. They are clumps of overgrown cells derived from the inside of blood vessels, or vascular endothelium. Cherry angiomas most commonly start appearing around age 40 and some estimates suggest that the major...
