Hidradenitis suppurativa (HS) is when recurring inflamed nodules (small, solid lumps) and cysts (fluid-filled mass) form in the armpits and groin. These may also be found under the breasts and around the nipples and anus.
The lesions start as plugged pores in the sweat and oil glands. Material builds up under the skin. The body's inflammatory system attacks these materials. This causes nodules and cysts to form. These lesions can burst under the skin and form an abscess. The area may have a bad smell and may heal and leave a scar.
It is rare to have another infection in these lesions. When it does occur, the bacterium is

Cortisone , taken orally for a few days, has shown to be effective in the short-term. Because of side effects, this drug should not be used over the long-term. Cortisone can also be injected or applied to the skin, which may reduce some of the side effects
Male Hormone (Androgen) Suppression
Controlling the male hormone (androgen) may also help. Examples include:
Small lesions can be treated in the doctor's office, which could require several visits. If your condition is severe, then a wide area may need to be removed. In these cases, a
