rash treatments on the body

Rashes can occur from a variety of factors including infections, heat, allergens, immune system disorders and medications. The most common rashes include eczema, psoriasis, poison ivy and heat rash. Infections that cause rashes are either fungal, bacterial or viral.

Rashes may cause discomfort or pain, as well as embarrassment about your skin’s appearance. Some rashes (heat rash and swimmer's itch) clear up on their own while others (rosacea and shingles) require medical treatment. Rashes lasting more than a few days that are unexplained should be evaluated by a doctor.
