[Takingthepain]

I have had this problem for about 2 months now. It was caused by over exercise, I was training to be a Marine. I have visited 2 doctors, and all they told me was to see a physical therapist, and that it was "Tendinitis".
I have pain in the outer part of my left ankle. I had to walk on it for work, and the condition just kept getting worse. I feel very stupid for not listening to my body. Over the last three weeks I have been doing stretches that my physical therapist told me to do. I have been in therapy for three weeks now, and nothing seems to get better. I got an X-Ray done on it and nothing showed up. I was wondering if Prolotherapy, MRI, or getting anything done to fix this condition so I can get on with my life.
