once i run, the knee
gets warmed up n its ok, but later it starts paining, especially on inner
side of knee
and back. once i fold the knee, and then open leg, i have to press back of knee to straighten it up, wonder what has gone wrong?once i rest 2 days or so, it improves but recurs after every running session. what should i do?take up swimming or cycling, less susceptible to injuries?any suggestions,less going to doctor again please???
