Signs and Symptoms
The groin and armpits have high concentrations of sweat glands, which is why these areas are most severely affected by hidradenitis suppurativa. There may also be lesions between the buttocks or under the breasts due to the friction from skin rubbing together, which is why people who are obese are more predisposed to this disease.

The lesions of hidradenitis suppurativa are firm tender, red bumps with extensive scar and sinus tracking under the surface of the skin. Often, you will see a pair of blackheads within one lesion, and the lesions may drain pus. Hidradenitis suppurativa lesions are rarely seen on the trunk of the body or on the scalp or legs.

Some people may experience only one or few lesions, while others may have severe disease, affecting many areas. Increasing hormones and excessive perspiration can cause more lesions.
