HS typically presents in areas of your body where the skin rubs together. Symptoms of HS include:

Blackheads: These small bumps often appear in pairs and small pitted areas of skin. Small, painful lumps: These lumps are often the size of a pea and appear in areas with hair follicles, sweat, and oil glands, as well as areas where skin rubs together.Tunnels: If you’ve experienced HS for an extended period, tracts that connect the lumps may form under the skin. These tend to heal slowly and may leak pus.

Hidradenitis suppurativa treatment

There’s currently no definitive cure for HS. Your healthcare provider or a dermatologist will determine a course of treatment that may include both medication and surgery.


The following medications are often used to treat HS:

Antibiotic creams: such as gentamicin (Gentak) and clindamycin (Cleocin)Oral antibiotics: such as clindamycin, doxycycline (Doryx), and rifampin (Rifadin)Tumor necrosis inhibitor (TNF) blockers: such as adalimumab (Humira)


In some cases, your healthcare provider may recommend a surgical procedure. Surgery for HS may include:

Unroofing: This is a procedure in which the skin is cut away to expose the tunnels.Limited unroofing: This procedure, also called punch debridement, is used to remove a single nodule.Electrosurgery: During this procedure, damaged tissue is removed.Laser therapy: This procedure is often done to treat and remove skin lesions.Surgical removal: With this procedure, all affected skin is removed.
