Find out how to treat your rash at home, as well as when a rash may require medical attention.

Rashes come in all different shapes, sizes, textures, and colors. Some are intensely itchy while others may burn or hurt. While rashes are typically innocuous and self-limiting, certain rashes may appear as a result of a serious underlying issue. It’s important to recognize when it’s time to turn to our Rockville, MD, dermatologists for your skin rash.

Causes of a Skin Rash

There are countless issues that can lead to a rash. Some of them include:

  • Allergies
  • Insect bites and stings (e.g., tick bites)
  • Bacterial or viral infections (e.g., shingles, chickenpox, measles)
  • Heat rash
  • Stress
  • Certain skin problems (e.g., eczema, rosacea, yeast infections)
  • Autoimmune diseases (e.g., lupus)
  • Drug reaction
  • Scarlet fever (more common in children)

At-Home Care Tips

Most rashes will clear up on their own. Some simple ways to ease any discomfort you may experience with your rash include:

  • Applying cold compresses to the area to reduce itching and swelling
  • Soaking in an oatmeal bath, which can soothe red, itchy skin
  • Not scratching the rash, as it could lead to infection
  • Applying calamine lotion if your rash is itchy
  • Applying over-the-counter anti-fungal cream to the rash if the rash is caused by a fungal infection (e.g., athlete’s foot, ringworm)
  • Using a hydrocortisone cream to reduce inflammation and itching caused by eczema

It’s important when to recognize that your rash needs more than just a little at-home care. It’s time to turn to our Rockville, MD, dermatologists if your skin rash:
