Common Types of Rashes

Published on March 1, 2019

A rash is a reaction causing abnormal texture or color on your skin. It may also lead to the formation of scales, redness, itchiness, inflammation, or pain. There are multiple causes of rashes including exposure to allergens, toxins, infections, or they may even be a symptom of a bigger disease.

It is important to know and identify the rash correctly so that you can seek proper treatment. Be sure to consult your dermatologist to treat your rashes. Here are five common types of rashes.

Hives

Hives can be triggered by a number of factors, including stress, certain types of food, insects, extreme cold or heat, or exposure to certain chemicals. In response to these factors, a chemical called histamine is released into the blood, which causes the expansion of tiny blood vessels in the skin and leakage of fluid in the uppermost layer. Accumulation of this fluid is what causes swelling and inflammation characteristic of hives.

It serves well to identify the trigger and avoid it. While they usually disappear on their own, you can use antihistamines to reduce the inflammation. A cold compress can also help relieve you of discomfort.

Eczema

Eczema is an umbrella term for skin conditions characterized by skin that is inflamed, red, itchy, and scaly. It is not contagious and affects both adults and children. It is a response to triggers such as climate, allergens, skin irritants, and stress.

The areas that are commonly affected by eczema include the eyelids, elbows, back of arms, hands and knees. The dryness and itchiness can lead to an itch-scratch cycle, which might break the skin, letting in harmful bacteria.

Athlete’s Foot

Athlete’s foot or tinea pedis is a common fungal infection affecting the skin on feet. It can spread to the toenails and hands. It occurs as a result of the growth of tinea fungus on the feet. The fungi is caught through direct contact with an infected person or surfaces contaminated with the fungus.

Symptoms include redness and itching on the soles of the feet or between the toes, crack in the skin, blisters, dry and raw skin. The fungus thrives and spreads in moist, warm environments like the spa, showers, and locker room floors. It is treated with topical antifungals.

Pityriasis Rosea

Pityriasis Rosea is a common skin condition often beginning as a large, scaly, pink patch of skin on the chest or back, followed by additional patches. These patches become itchy along with redness and inflammation. Areas affected include the neck, chest, upper arms, abdomen, back, and legs.

The cause of pityriasis rosea remains unknown though there is evidence suggesting that it is viral. Although treatment is not necessary in mild cases, oral antihistamines can help soothe itching.

Herpes

Herpes is a viral infection characterized by the formation of painful, open ulcers. The initial tingling and redness eventually form lesions that join into open weeping sores. The virus can be transmitted from the sore or body fluids of an infected person.

The virus lives in the nerve and the infection can recur in the same area on your body. An antiviral medication reduces the number, severity and duration of herpes outbreaks.
