From my experience with injuries, going to a good orthopedic who can provide specific stretches is almost always the answer.

Secondly, to keep things in order after the pain subsides - Kettlebell swings, traditional 2 arm and 1 arm I find are fantastic for evening out the 2 sides of the body. Possibly yoga, definitely swimming, and for sure buy a good tens unit, because they feel amazing and can help alot.
