I had pretty bad ITB problems a few years back. I got rid of it completely with PT centered around weights. My PT bascially explained that when the quad is not strong enough to do the job that it is being asked to do, it will, shut down and the ITB will bear the brunt of the imbalance. The problems is gone. No shots, no surgery..gone.
See a good sport medicine doc, get some good PT going, strengthen and balance your leg muscles. I know everybody is different, but I betcha it will work.
