Hidradenitis suppurativa (HS) is an inflammatory condition of the hair follicle. Recurrent, inflamed nodules and cysts form in the armpits and groin. These may also be found under the breasts, and around the nipples and anus. Less commonly other areas of the body can be affected.

If you smoke, talk to your doctor about finding a program to help you quit. It is also important to maintain a healthy weight and eat a healthful diet. If you need help with losing weight, consider talking to a dietitian who can help you with meal planning.
Your doctor may prescribe one or more therapies depending on the severity of your HS.
Corticosteroids may help improve symptoms. These can be taken by mouth, applied to the skin, or injected into the area.
Other medications called biologics, which decrease the bodies immune response, may be used in severe cases. These medications have many risks, so your doctor will carefully weigh the risks and benefits of using these.
Small lesions can be treated in the doctor's office. The sores may be cut open and allowed to drain. If your condition is severe, then a wide area may need to be removed. In these cases, a skin graft may be needed.
