Annoying leg pain

Recently when I have been pitching I get a slightly annoying pain in my drive leg, below my calf and above my ankle, on the inside part. I have no idea why this happens and it’s nothing I can’t deal with but I was just wondering what may be causing this.

Sounds a little like shin splints, which can happen from just over using your legs. Probably doesn’t happen very often from pitching, usually I have probelms with shin splints from running. But if that’s what it is, then there’s nothing to worry about. Ice your legs and rest. Be sure you’re stretching properly before and after you pitch.
