What is a skin rash?
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. They can be dry, moist, bumpy, smooth, cracked, or blistered; they can be painful, itch, and even change colour.
