Overview
Hidradenitis suppurativa is a chronic skin condition characterized by blockage of the sweat glands and subsequent inflammation and infection of the deeper skin structures. In people who are prone to hidradenitis suppurativa, the sweat glands of the armpit, belly, buttocks, and/or groin become clogged, causing large, tender red bumps to grow in these areas. The bumps represent inflammation, and over time these will become infected with bacteria; multiple bumps can grow together under the skin into large, painful cysts. These cysts can reach the surface of the skin and drain pus. The cycle of plugging, enlargement, and draining will eventually lead to scarring of the skin.
There is no cure for hidradenitis suppurativa, but your doctor can help you develop a strategy for treating existing lesions and preventing new ones.
