WTF is this on the bottom of my heel? I got it last year when I started running regularly, and it is slowly getting more and more painful. It's hard like a callus, but it has a hole in the center. It's fine unless there is pressure on it, then I get a sharp pain. I've tried shaving it off with a razor blade, but I cannot remove it all until the hole goes away, it's too deep.

Any thoughts? Aids? Herpes? Avian bird sars?
