Hello. Thank you for your message.

We have had several questions about rashes lately.   We cannot know what is causing your rash, but I can give you some general information.

Rash is not a specific diagnosis. Instead, it refers to any sort of inflammation and/or discoloration that distorts the skin's normal appearance.  Common rashes include eczema, poison ivy, hives, and athlete's foot.
Infections that cause rashes may be fungal, bacterial, parasitic, or viral.
Over-the-counter products may be helpful treatments for many skin rashes.
Rashes lasting more than a few days, that worsen or that are unexplained should be evaluated by a doctor.
