I recently began feeling a pretty intense pain in my left ankle. Basically, if I put pressure on the arch of my foot (inside) I get a pain that starts there, and goes up around the front of my ankle, and ends at the back of the calf. The pain can be described as a stiffness, much like you would feel if you were overstretching a muscle. There's no swelling to speak of. I've actually had this a couple times in the past, and it seems to go away after a while. I was just wondering what the cause could be. I was thinking maybe tendonitis.
