I'd first like to start off by showing you the piece of skin on my hand:

A description of it would be an extra circular layer of skin that sticks out of my hand. I didn't always have this. I noticed it formed about 15 months ago. I haven't done anything to it since I thought it would fix on it's own, but it just hasn't. It doesn't hurt or affect me, but it looks weird. Does anyone know what this is? How could I go about fixing this? I don't want to see a dermatologist unless it's a serious issue.
