Callus on my thumb
When I was a baby, I used to suck my thumb, then when I started getting my baby teeth I started teething on it instead of sucking it, and eventually I started biting at the skin on my thumb until it was raw (to be specific, the knuckle right below the thumb nail)... So eventually the skin on my knuckle began to callus it self, and I developed a habbit of pulling at it... and I've been doing it for over 20 years... the knuckle on my thumb is so callused up that the creases in the knuckle are completely gone... and it's so thick that if anything touches it I don't even feel a thing
Does anyone know this would even be called, am I the only one who has this? and is there a way I can get rid of it?
