All that advice about stretching is great, but I'm still standing by getting a second opinion from a different doctor. There is a possibility that the stretches are actually making the problem worse because the real problem was misdiagnosed.

Being told for three months to do stretches and mild weight lifting to fix tendonitis in my shoulder when I actually had a torn ligament that should have been treated with non-use and in a sling is why I still have a lot of pain and limited mobility 6 months after it tore.
