What Caused My Rash?

Be able to recognize when your rash is a sign of something more serious.

Rashes are an incredibly common problem and are typically nothing serious. Of course, a rash that’s itchy or inflamed can certainly be annoying, and you may be wondering whether you should just try to treat the problem on your own or if you should turn to our Huntington and Hicksville NY dermatologists Dr. Daniel Sherer and Dr. Todd Coven. Since a rash may be a sign of something else going on in the body, it’s important to understand when to see a doctor.

Common causes of rashes include:

• Poison ivy, oak, or sumac
• Heat rash
• Diaper rash
• Stress
• Eczema (also called atopic dermatitis)
• Psoriasis
• Contact dermatitis
• Rosacea
• Chickenpox
• Certain medications
• Shingles (more common in older adults)

Sometimes a rash is a sign of a fungal (e.g. ringworm), parasitic, bacterial, or viral infection. A rash caused by a viral infection will typically clear up on its own after the virus has gone away; however, bacterial, fungal, or parasitic infections that cause rashes need to be treated by your Huntington dermatology office, usually with medication. Of course, a rash can also be a sign of another underlying issue such as an autoimmune disorder or a thyroid problem.

You should see your Huntington dermatology team about your rash if you are experiencing any of the following symptoms:

• A rash that appeared suddenly and is spreading quickly (this could be a sign of an allergic reaction to something you ate or a medication you are taking)
• A rash that is accompanied by a fever
• A rash that lasts weeks and doesn’t improve with home care
• A rash that has swelling or bruising around it
• A rash that oozes or has a bad odor (these are signs of infection)
• A rash that looks like a bullseye (could be a sign of Lyme disease)
• Any yellowing or hardening of the skin

Minor rashes can typically be treated at home just by:

• Avoiding coming in contact with the substance or allergen
• Keeping the rash exposed to the air (do not cover it)
• Apply cold compresses to the area if it’s irritated or itchy
• Applying calamine lotion to help with the itching
• Taking an antihistamine if you’re dealing with hives or a mild allergic reaction

If you are concerned about a rash but you aren’t quite feeling comfortable coming into Huntington dermatology or Hicksville office, our dermatologists also offer telemedicine visits. This means that you can schedule a virtual appointment with your doctor to find out whether your rash is a problem that requires immediate attention or simple home care.
