Im assuming this is a dermatology issue. But my husband has a small hole ( kinda like a big pimple that has popped)in the groin area, between his leg and scrotum. It looks as though it is over a blood vessel. He says it is very painful. I told him to give up whitey tighties for a while, but im wondering if any one knows what it could be and how to get it to heal. (it has been there for about a week and doesnt look any better)
