gooses foot?

I injured my knee back in dec. I may have partially dislocated my knee. I've been seeing an orth. since March and he's at a loss for why I'm still in pain. My leg is still sore at the gooses foot(pes anserium bursitis) and patella tendonitous. I had a cortisone shot and it made it feel worse. My MRI has been normal. My quad muscle has been painfully sore to. I'd appreciate any suggestions, my doc has given up. I'm alleric to all anit inflamitories and have yet to found anything to help with the pain thankyou
