If you’re suffering from IT band pain, you can apply many of the above methods. You need to strengthen any weak muscles as much as possible. Ensure that you are stretching your outer hip muscles, too.
Anything you can do to loosen the IT band and prevent it from tightening will help exponentially. Just know that you may be looking at several weeks for the band to fully heal.
If you have fractured any part of your hip, a simple X-ray may not reveal it. In order to be certain, you should have an MRI scan. This will catch anything that an X-ray might have missed.
