Hello @jonimclin, Welcome to Connect. Sorry to hear you still having some pain at your current dosage of Prednisone. You might find the following discussion helpful:

Did you have the stiffness in the left shoulder and pain in the left hip when you first started treatment 20 months ago or is this new?

I am at 28 months on prednisone, started at 20 mg and down to 5. As I got closer to 5 I started having significant pain in different spots in my right shoulder and had an episode of severe right hip pain at 5 mg. The PMR pain I have affects both sides so I did not think it was that. I'm a retired PT and self-assessed the shoulder issue as bursitis. It's different from PMR pain, just in small areas and right where there are bursas. I went to urgent care for the hip and they took an x-ray. I do not have significant arthritis and the doctor thought it was "soft tissue". Again I self-assessed and believe it is iliopsoas bursitis. It could be that the prednisone masked these problems which were developing with age (74). It could also be that PMR and/or the drugs I take for it (prednisone and methotrexate) cause damage in the shoulders and hips.
