Been having knee pain for a few months now. Finally went to the Doc. She x rayed and didn't see any problems. Told me to RICE and limit activity for a few days and is referring me to an ortho doc. In the meantime, I've been doing some research, and it is almost certainly patellafemoral pain syndrome. Anybody have any experience with this? What worked to recover and how long before I can expect to be back to normal? Thanks.
