Well... I've had this spot on my foot for a few years now, and its like... a hole... with really rough skin around it and inside the rough skin are little spots of like... black or brown. Its on my left foot, right in the middle of that area. It used to hurt quite a lot, but it doesn't anymore. Im just afraid if I don't treat it eventually, it will just get worse. Im not sure what to call it either, I've never seen anything quite like it... I wanted to google it, but had nothing to go on. So any help or suggestions would be helpful. Thanks.
