Hidradenitis?: It sounds like you might have hidradenitis suppurativa, which is a condition where sweat glands become chronically infected, forming boils or abscesses. It commonly occurs in the armpits and groin but can happen in other places also. You need to see a doctor for this. Treatment can include chronic antibiotics and sometimes even surgery.

Hidradenitis: This is probably hidradenitis suppurativa or also called apocrine acne. You may need surgical therapy. See a dermatologist first. He or she can tell you what is best.
