Please make an appointment with a hip orthopedic surgeon to make sure you don't have any hip problems. I actually had an impingement between my pelvic bone and my femur. It was solved by an adjustment in how I walked and set. It took the pressure off the impingement and allowed that inflammation to recede. Also ask if you have trochanter bursitis, that can really hurt and cause all manner of problems in your upper legs. I have been off prednisone for over 6 moths and the bursitis is chronic. I am treated by a sports medicine doctor now. Initially my Rheumy gave me steroid injections for the bursitis. I actually self-diagnosed the bursitis then saw an ortho for a medical diagnosis. Please go after the pain areas one at a time and see other specialists. I did and discovered that even if PMR is the initial cause of the problems it may no longer be the only problem that needs treatment. No doubt that PMR caused my impingement to surface and no doubt PMR caused the bursitis, but oral steroids were never going to solve these problems.
