Relief starts with the right diagnosis

A skin rash can appear suddenly or develop gradually. It may itch, burn, flake, blister, or simply change the appearance of your skin. While many rashes are harmless and temporary, others can signal an underlying medical condition that requires prompt treatment. Because many rashes look alike but have different causes, an accurate diagnosis is essential.

Dr. Chynna Steele Johnson, a board-certified dermatologist, and her team at Steele Dermatology evaluate rashes in patients of all ages. Whether you’ve developed a new rash, have a persistent skin irritation that won’t improve, or have experienced recurring flare-ups for years, we work to identify the cause and develop a personalized treatment plan to help restore your skin.

What is a skin rash?

A skin rash is a broad term for any noticeable change in the skin’s color, texture, or appearance. The medical term for rash, dermatitis, simply means inflammation of the skin. Skin rashes may affect a small area or spread across larger portions of the body. Some develop quickly after an exposure, while others progress over days or weeks.

Because the skin can react to infections, allergies, autoimmune conditions, medications, environmental factors, and chronic inflammatory diseases, there is no universal treatment for every rash. The first step is to determine what is causing it.

Common symptoms

Redness or discoloration
Itching
Burning or stinging
Dry, flaky, or scaly skin
Raised bumps or plaques
Blisters or fluid-filled lesions
Swelling
Cracking skin
Pain or tenderness
Oozing or crusting

Some rashes come and go, while others continue to worsen without medical care.

Prescription topical creams or ointments
Moisturizers and skin barrier repair products
Oral medications
Antihistamines
Topical or oral antifungal medications
Antibiotics when appropriate

For chronic inflammatory conditions like eczema or psoriasis, ongoing management may help reduce flare-ups and improve long-term skin health.

How are skin rashes diagnosed?

Diagnosis begins with a thorough medical history and skin examination. Dr. Johnson will evaluate:

When the rash began
Whether it itches, burns, or causes pain
Recent illnesses or medication changes
New skincare products, detergents, or environmental exposures
Family or personal history of skin conditions

When necessary, additional testing may include:

Skin biopsy
Skin scraping
Fungal testing
Patch testing for allergic contact dermatitis
Laboratory testing when an underlying medical condition is suspected

An accurate diagnosis helps avoid unnecessary treatments and speeds recovery.

Can stress cause a rash?

Yes. Stress can trigger or worsen several skin conditions, including eczema, psoriasis, hives, and rosacea. While stress may not be the sole cause, it often contributes to flare-ups.

Should I use over-the-counter creams before seeing a dermatologist?

Some over-the-counter products may temporarily relieve symptoms, but using the wrong medication can sometimes worsen certain rashes or make diagnosis more difficult. If your rash persists or is worsening, professional evaluation is recommended.

Are rashes contagious?

Some are, but many are not. Fungal infections and certain viral or bacterial rashes can spread, while eczema, psoriasis, allergic reactions, and many inflammatory skin conditions cannot.

Will my rash come back?

Some rashes resolve completely after treatment, while chronic conditions such as eczema or psoriasis may flare periodically. Proper diagnosis and ongoing management can often reduce the frequency and severity of recurrences.
