Hidradenitis suppurativa (HS) is a painful, long-term skin condition that causes abscesses and scarring on the skin.
The exact cause of hidradenitis suppurativa is unknown, but it occurs near hair follicles where there are sweat glands, usually around the groin, buttocks, breasts and armpits.
For reasons that are unclear, more women than men have the condition. It’s thought to affect about 1% of the population.
