How can I treat a rash on my back?
assistant
The first step to treating a rash is to identify the cause. If it's an allergic reaction, you may be able to reduce symptoms by avoiding certain triggers and using over-the-counter antihistamines. You could also try applying calamine lotion or aloe vera gel to help soothe the skin. If the rash persists, consult your doctor for further treatment options.
