Overview
A skin rash is a change in the skin’s appearance that can include redness, bumps, itching, or scaling. Causes range from allergies and irritants to infections and chronic skin conditions.
When to see a doctor
See a doctor if a rash spreads quickly, is painful, involves the face or genitals, appears infected, or is accompanied by fever or difficulty breathing.
What you should know
A dermatologist can identify the type of rash and recommend treatment, which may include topical creams, antihistamines, or other medications.
Avoiding known irritants or allergens helps prevent recurrence.
