A 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 that last more than a few days or are unresponsive to over-the-counter products should be evaluated by a dermatologist.
