What is hidradenitis suppurativa?
Hidradenitis suppurativa (HS) is a skin disease. It causes deep, painful boils or pockets of infection (abscesses) in your skin. These abscesses grow when the deep roots of hair follicles get blocked. A hair follicle is the base (root) of a hair.
HS commonly occurs in areas where skin rubs together such as armpits and in the genital and anal areas. But they may also be found elsewhere, such as the neck or scalp. When these glands become blocked, they fill with fluid and can become infected. They then burst, and the infection spreads. This causes larger areas of swelling, infection, and abscesses that can spread through the layers of skin.
Hidradenitis suppurativa is also known as acne inversa. But it is not a form of acne. It is also not contagious. It is an ongoing health problem that flares up, goes away for a while, and then comes back. In women, symptoms may get worse before a menstrual period and then go away after. Over time, you may find that the flare-ups don’t go away and your skin can become scarred. Early treatment is important to prevent HS from getting worse.
