Hi, I have been having for the past several years now bumps sometimes painful under my armpit with a foul odor when popped. Also I get boil like bumps, blackheads, and whiteheads on my inner thigh, groin area, and sometimes my vaginal area. I have many crater like scars from the boil like bumps and tiny red scars from the smaller bumps. What is this and how do I get rid of them and prevent them from coming back?
