While skin rashes can be both uncomfortable and unsightly, they also may be alarming. Because there are several causes with varying degrees of severity, it can be challenging to know when to self-treat instead of contacting your dermatologist. Here’s a closer look at skin rashes and how to determine if they need professional attention. 

What Caused the Rash?

There are many causes for skin rashes, some more serious than others. While a mild reaction to the sun or irritation caused by grass isn’t usually a cause for concern, some rashes can be an indication of a larger issue. Understanding the cause of an outbreak can help you determine whether a topical cream will help or if it's time to visit your dermatologist.

If you have a preexisting condition, such as eczema, atopic dermatitis, or psoriasis, you may already know how to treat a flare-up without contacting your doctor. However, if a rash comes on suddenly without any recognizable cause, it may be worth calling a professional. 

How Big Is It?

The size of a rash can also indicate the level of severity. If the outbreak is small or centralized to only a minor patch of skin, it can likely be addressed with an over-the-counter treatment.

However, skin rashes that cover large portions of your body may be a sign of a more serious issue, including an allergic reaction or an infection. Likewise, a rash that comes on suddenly and spreads quickly is another cause for concern that should likely be addressed by a specialist. 

Is It Painful?

While itching is one of the most common symptoms of a rash, some conditions may also cause pain or discomfort. Conditions like shingles—caused by the same virus that causes chickenpox—can result in severe pain and blistering. While shingles are only contagious to individuals who aren't immune to chickenpox, they can be highly dangerous. Pain is often an indication of a more serious condition and should always be evaluated by a health care professional.
