Rashes Q & A

What are rashes?

Rashes are areas of irritated or swollen skin. They may appear as blotchy areas of skin, welts, or blisters. Your rash may be itchy, painful, scaly, or dry.

Your rash may appear on one area of your body or all over. It may appear suddenly and resolve on its own or turn into a chronic skin condition. Rashes may also come and go. 

What are the types of rashes?

There are many types of rashes that develop from various causes. These types include:

Contact dermatitis

Contact dermatitis is a skin rash that develops when your skin comes in contact with an irritating substance, such as detergents, chemicals, or dyes. Poison ivy also causes this type of skin rash.


Eczema is a chronic type of rash that causes inflamed, itchy patches of skin. This type of rash occurs in cycles, and flare-ups may be unpredictable.

People with eczema may also have asthma or hay fever. 


Psoriasis is an autoimmune disorder that triggers an overproduction of skin cells. People with psoriasis have red, scaly patches of skin. It is a chronic skin condition. 

Your rash may also be a symptom of an underlying medical condition such as rheumatoid arthritis or lupus or an allergic reaction to a drug or food. 

When should I get dermatology care for rashes?

Though you may be able to treat some rashes at home, you should schedule an appointment with the experts at Thomas Dermatology if at-home care fails to improve your skin condition. 

The team also recommends you come in for an evaluation if your rash is itchy or painful or a chronic problem. They also recommend scheduling a visit if your rash develops suddenly and covers a large portion of your body. 

The experienced dermatologists conduct comprehensive evaluations to find the root cause of your rash so you can get the most effective treatment.

The full-service dermatology practice even has an on-site pathology lab and offers allergy testing. 

How are rashes treated?

The Thomas Dermatology team customizes your rash treatment plan based on the underlying cause and the severity of your symptoms. Initial treatment focuses on easing your symptoms and may include cortisone cream, antihistamines, or corticosteroids.

Your treatment plan also focuses on addressing the underlying cause of your rash. For example, with contact dermatitis, the team helps you create a plan to avoid the irritating substance that causes your rash. 

Rashes may be a sign of an underlying medical condition. For help with your rash, call Thomas Dermatology or book an appointment online today.
