CystsCysts are oil filled sacs below the skin surface; they can form anywhere on the body, including the scalp.  Cysts can get inflamed, especially if the contents of the cyst ruptures into the surrounding skin.  This makes them red and painful, and sometimes drainage is required.  Small cysts do not necessarily need treatment, but if they are unsightly, they can be removed with a minor surgical procedure. Larger cysts can be removed in our office if they become inflamed and rupture.
