I had surgery about 5 weeks ago for a torn miniscus and to clean out gouty crystals. Doing therapy, but is it normal to have severe pain ( level 8) when doing straight leg lifts.also there is loud crunching in my knee when I attempt to extend my leg. Should I have an ex ray to see if something is wrong? I am concerned the therapy my be doing more harm than good. Before surgery I was told this was a cure all and I would not need therapy. Not at all what was explained to me.
