Abscess : Hi, an abscess is the body's way of "walling off" an infection it cannot fight on its own. It will be a growing, warm, red, tender mass, and could form anywhere on the body. Tx often consists of incision and draining of pus, heat, rest, and possible antibiotics. Recurrent axillary abscess' are called hidradenitis supprativa, responds to sugery, laser, and restriction of close shaving practices.
