Get thee to a physical therapist!!!!!!
It would probably be good to have that ankle re-evaluated by an orthopod- I suggest one who deals with sports injuries and rehab.
You will need to see a doc anyway to get a physical therapy referral.
Once you start therapy, DO YOUR EXERCISES!!!!!!
No skipping because you are tired or busy or because they get boring. Keep up with the exercises after therapy ends. You've got to keep strong muscle support around that ankle.
Also, ask about a technique/manipulation some therapists can do that releases/ realigns tendons. I can't remember the name exactly, something like myo-fascial release?? It can work wonders to return range of motion and relieve pain.
Did I mention, DO YOUR EXERCISES!!!!!
I speak from experience on all of the above. My ankle history sounds similar to yours. It took nearly 3 years till all was well, once I found the right doc and returned to therapy. Had the release thing done - a true miracle!!!
By the way, how did you find your way to a nursing B.B. from mini storage? Hope we have been of help!
