What is hidradenitis suppurativa?

“Hidradenitis” is a Greek word that means “inflammation of the sweat glands”, and “suppurativa” means “pus-forming”, which can be a more severe symptom of the condition.

HS is a chronic, long-term skin disease. It causes swollen, red lumps under the skin (which can be large sometimes) that are often very painful, sore or tender. These lumps sometimes leak pus, which can create an unpleasant-smelling odour. In HS, these lumps tend to grow around the armpit and groin/genital areas, but it’s also common for them to grow under the breasts, on the buttocks and/or on the inner thighs.

The soreness, inflammation and pus from HS may resemble “bad” pimples. But HS is not acne; it is an entirely different condition.
