I have also neen diagnosed with bursitis of the hip. I have just finished two weeks of physical therapy after trying pain medication (celebrex), cortisone shot, new mattress, etc... I feel the physical therapy is helping a lot so far. I can hardly believe it. What seems to help the most is the ultrasound and massage of the hip with the cortisone cream. I understand what you are saying about not being able to sleep well. let me know if you have any improvement. My PT says it takes a long time to get this better.
