L73.2: Hidradenitis suppurativa

Certain parts of your hirsute skin have become inflamed.

Every hair is anchored in a small bulb, the hair follicle. Sebaceous glands are usually attached to these hair follicles. The sebaceous glands produce an oily substance for the skin called sebum. Sebum prevents the skin from drying out.

The pores of your skin have become blocked. It is usually the pores in the armpits, groins or buttocks that are affected. Your skin is badly inflamed in those areas. Red nodules usually form on and in the skin that are often painful. Pus-filled cysts and wounds often appear later on. This skin condition can cause severe restrictions to a person’s everyday life. There may also be psychological effects.
