Following a 1/2 marathon I had run back in November, I was diagnosed with patellar subluxation after coming down with a persistant case of medial knee pain. I have been doing strength exercises RX by my physcial therapist with out any noticeable improvement. Now I have a new problem. If I apply pressure or if my pants simply touch the medial side of my knee (at the joint line) I get an intense "pins and needles" sensation on the left side of my knee. This has led to a constant numbness on the lateral side of my knee that has been present for almost two weeks. I am headed back to the Dr. next week, but just wanted to see if anyone has dealt with anything similar to this.
