Symptoms
By Mayo Clinic staff
Hidradenitis suppurativa commonly occurs around hair follicles where many oil and sweat glands are found, such as the armpits, groin and anal area. It may also occur in areas where skin rubs together, such as the inner thighs, under the breasts or between the buttocks. Hidradenitis suppurativa can affect a single area or multiple areas of the body.
Signs and symptoms of hidradenitis suppurativa include:
- Small pitted areas of skin containing blackheads, often appearing in pairs or a "double-barrel" pattern.
- One or more red, tender bumps (lesions) that fill with pus. The bumps often enlarge, break open and drain pus. The drainage may have an unpleasant odor. Itching, burning and excessive sweating may accompany the bumps.
- Painful, pea-sized lumps that grow under the skin. These hard lumps, which may persist for years, can enlarge and become inflamed.
- Painful bumps or sores that continually leak fluid. These open wounds heal very slowly, if at all, often leading to scarring and the development of tunnels under the skin.
Hidradenitis suppurative often starts at puberty with a single, painful bump that persists for weeks or months. For some people, the disease progressively worsens and affects multiple areas of their body. Other people experience only mild symptoms. Excess weight, stress, hormonal changes, heat or excessive perspiration can worsen symptoms.
When to see a doctor
Mild cases of hidradenitis suppurativa may be treated with self-care measures. But if the condition doesn't improve in one to two weeks, appears in several locations, recurs often or is painful, consult your doctor or a dermatologist. Most often, medical treatments — such as prescription medications or surgery — are necessary to manage the problem.
