Hi, I’m sorry about your unresponsive pain, and I hope you have figured something out by now. What is your pain Effer in your neck, shoulders, and hips? If not, then I would certainly wonder if I was misdiagnosed. If you increase the dosage of prednisone and the pain doesn’t resolve, and that is also indicative and it’s some thing other than PMR in most professionals opinions from what I’ve read.

Regarding your knee pain and the doctor telling you you have arthritis in your hip, the knee is a common spot for referred pain from the hip:

“If you have a problem with your hip joint you may feel pain in the groin, down the front of the leg and in the knee. Sometimes knee pain is the only sign of a hip problem – this is called referred pain or radiated pain and is fairly common.” (From the website Versus Arthritis.)
