An abscess is an inflamed and infected pocket of pus in the skin. It is often called a boil. Incision (cut) and drainage is a procedure to drain pus from an abscess.

Drainage of an abscess is the preferred treatment to clear an abscess. It is often used if the abscess is large, growing, painful, or not improving on its own.

Do not pop or cut an abscess yourself. This can spread infection and make it worse.
