Are you sure it is Bursitis and not Avascular Necrosis. I was treated for bursitis and also did the Injections and was sent to a Ortho by my GP and was diagnosed with AVN. My AVN was caused by steroid injections from other injuries in the past years. This year I have had both my hips replaced due to the steroids and the AVN. Be careful with the steroid injections. Get checked for AVN. The earlier detected the more options you have. Be Careful!!
