Just re-starting to run after almost 10 years away and a history of ankle sprains (twice each) & knee cartilage operations. Trouble is, I get severe pains in my feet, seems to come from inside the foot and around the ankles, almost as if the joint is unstable. I have no trouble walking, but running provokes this. It is very frustrating as I would dearly love to get back to regular running. Could this be just due to lack of conditioning in the joints - any thoughts/suggestions to deal with it ?
