What it means
A rash is a change in the skin's color, texture, or appearance. It may appear as redness, bumps, blisters, scales, or patches. Rashes have many causes, including allergic reactions, infections such as chickenpox or Lyme disease, contact with irritants, autoimmune diseases, and medication side effects. Some rashes are harmless and clear up on their own; others require treatment. Seek care right away if a rash spreads rapidly, covers a large area, is accompanied by fever, affects the face or genitals, or is painful and blistering, as these may indicate a serious condition.
