Rash

Skin rashes are a common condition that can occur at any time in life. Skin rashes can be caused by a variety of things, from allergic reactions and infections to chronic skin conditions and stress. In order to get the right treatment and relieve your symptoms, it is important to first identify what is causing the rash.

Symptoms and causes of skin rashes

Skin rashes can look different and have many underlying causes. Most skin rashes are harmless and will go away with proper treatment. Here are some common rashes:

Eczema

Eczema often appears as dry, itchy, red rashes on the skin. Eczema can be caused by genetic factors, allergies, or contact with irritants such as nickel or detergents. Atopic eczema is the most common form. It mainly affects young children, but can persist or occur in adulthood.

Allergy

Skin rashes due to allergies can occur after contact with allergens such as pollen, animal dander, certain foods or medications. Common symptoms include redness, swelling and an intensely itchy rash. Hives are a common allergic skin rash that occurs suddenly and can change shape and move quickly over large areas of the body.

Infections

Viral infections such as herpes , shingles, and cold sores can cause characteristic skin rashes. Herpes causes small, painful blisters, often around the mouth or in the genitals. Shingles causes painful blisters that are often on one side of the body. Cold sores are a common illness in children that are characterized by small blisters, mainly in the mouth but also on other parts of the body.

Sponge

Some types of fungi can cause skin diseases such as athlete's foot and ringworm. Athlete's foot causes flaky, scaly skin between the toes. It can sting, itch and cause the skin to crack. Ringworm can occur anywhere on the body and appears as a ring-shaped, itchy rash.

Insect bites

Bites and stings from insects such as wasps, ticks, lice and scabies can lead to rashes. Wasp stings often cause immediate pain, redness and swelling. Tick bites can sometimes lead to more serious conditions such as Lyme disease and TBE. Lice or scabies are primarily noticeable through intense itching.

Other skin rashes

Acne is caused by inflamed oil glands and appears as blackheads, raised yellow or red bumps, and sometimes large, tender lumps under the skin. Psoriasis causes large, red, scaly rashes, often on the elbows, knees, lower back, and scalp. Rosacea causes redness, tingling, dilated superficial blood vessels, and sometimes small bumps on the face.

Stress rash

Stress rashes can occur as a direct reaction to emotional or physical stress and often manifest as itchy, red rashes. Stress can also worsen other skin conditions such as acne, eczema and psoriasis.

Diagnosis and treatment of skin rashes

How you treat a rash depends on what's causing it, but some rashes go away on their own and don't need treatment.

If the rash is caused by dry skin, it may help to apply an emollient cream frequently. Rashes that are dry, red, and itchy can be treated with an over-the-counter cortisone cream.

If over-the-counter medications don't help or if you don't know what's causing your rash, you should seek medical attention. You should also contact your healthcare provider if you have had long-term problems or feel worried about your rash.

Call 911 or go to the nearest emergency room if you or someone close to you has a sudden allergic reaction with a rash, difficulty breathing, and swollen lips, throat, or face. This may be a sign of anaphylactic shock.
