I've had this big callous on the top of my hand, on my index finger knuckle. I know callouses are caused by repeated rubbing or gripping something too hard, but how does that occur in a place where that's impossible?
Is there any way to make it go away? I've had it for many years, and it's just kind of unsightly. I've attached a picture.
