I went in to see physiotherapist to have gait analysis as I was getting a pain on the inside of my left Knee. Anyway, to cut a long story short, I didn't even get to the gait analysis as my problems is that I have one leg approx 2cm longer than the other starting from the pelvis. Have been given exercises to do every day for 2 weeks and not to run in that time. After 2 weeks I am to run for 10 mins on treadmill and see if pain is still there. Has anyone else had this problem?
