Overview

Hidradenitis suppurativa (hi-drad-uh-NIE-tis sup-yoo-ruh-TIE-vuh) is a condition that causes small, painful lumps to form under the skin. The lumps usually develop in areas where your skin rubs together, such as the armpits, groin, buttocks and breasts. The lumps heal slowly, recur, and can lead to tunnels under the skin and scarring.

Hidradenitis suppurativa tends to start after puberty. It can persist for many years and worsen over time, with serious effects on your daily life and emotional well-being. Combined medical and surgical therapy can help manage the disease and prevent complications.
