I am 25 and always had pain and stiffness in my right knee which always seemed worse in cold damp weather, I put this down to a bit of arthirtis but never had it diagnosed.

After starting at the gym my left knee started being very painful, its stiff in morning, it sometimes feels warm but no swelling. I went to the gp and he told me that it wasn't arthiritis, he said it was a displaced knee and told me swimming and leg strengthening exercises to strengthen up the tendons.

I therefore started swimming, but htere hasbeen no significant improvement, it still is worse with damp cold weather. Some days it is sp bad that I can't srive my car or even get up or down the stairs, I am also having difficulty sitting down and getting up of the toilet or settee.

Please advise! Is it possible to have 2 displaced knees?
