So far everyone's advice is spot on. Doc, PT, and something no one mentioned that a lot of top Olympic athletes do is: visualization. The concept involves seeing the injury area as it should look when healthy. Then as you exercise you visualize the healthy joint. I have used this for myself and student athletes. Both for injury, studies and to view one successful on the mat before a match.
Never under estimate the power of the mind.
I've been laughed at for this concept but I don't care because I know it works. Seeing, & experiencing is the truth in the mustard.
