Hey Folks, need your input. In agony here when I try to straighten my left leg. When my knee gets to about 30 degrees the kneecap seems to move up slightly and click, that is when I am in extreme pain. It has been doing that for as long as I can remenber (only without the pain) but in the last six weeks or so the pain has been eyewatering. Doc referred me to a physiotherapist who is now referring me for a scan. Anyone had this? What was wrong and how was it fixed?
