Ok you can call me stupid or whatever you want, I was rather dumb in my youth. I have been chewing on the side of my thumb, but I figured it would just grow back, but it really started to callous. Stupidly I kept chewing and chewing on it cusae it botherd me and I wanted it to go away. But now its so calloused that its about a quarter of an inch long on the side of my thumb, and theres a y shaped crack in it that if I move too much, it bleeds

well thats all I can think to tell... Any of you got any ideas on how to get rid of it?
