yes i have been having a knee condition for over a year ever since i fell onto some rocks every time i crouch down and stand up again i get this aching pain on the top and the out side of my knees i have been to the doctor but no luck they have done blood work and x rays have ruled out auto immune, arthritis, lhyme disease and everything else some one could test for with x rays and blood work but still no result ever since the accident my legs fall asleep when i cross my legs which they never did before the accident when i am in humidity the pain lessens i just want any possible idea i have thought about petelofemural pain syndrome but still not sure.
