: I have a pain that starts on the lateral side of my left foot (not in the heel and not in the toes). Directly in the middle of my foot. When I walk, pushing off to walk sends a pain from the lateral side of my foot, directly over the top middle of my foot and thru my ankle. It's been for about a week now. I can't stand on my tip-toes (or ball of my foot) because the pain is excrutiating. I'm limping now, and have looked at every website, but found nothing.
Guessing that you may have posterior tibial tendinitis. This tendon runs from behind the calf to the middle of the ankle/foot. Check with your physician/podiatrist.
