A rash is defined as a widespread eruption of skin lesions; it is a very broad medical term. Rashes can vary in appearance greatly, and there are many potential causes. Because of the variety, there is also a wide range of treatments.
A rash can be local to just one small part of the body, or it can cover a large area. Rashes come in many forms; they can be dry, moist, bumpy, smooth, cracked, or blistered; they can be painful, itch, and even change color.
Rashes affect millions of people across the world; some rashes may need no treatment and will clear up on their own, some can be treated at home; others might be a sign of something more serious.
