Hello @cliffg26, Welcome to Connect. There are several conditions that mimic PMR. I'm not a doctor but it might be as simple as you don't actually have PMR. Here is more information that explains it much better than I can.

"If there is not adequate improvement with an appropriate dose of prednisone within one to two weeks, reconsider the diagnosis. If clinical suspicion for PMR remains, consider trialing a higher prednisone dose (usually up to 30 mg) after discussing with the local rheumatology service."

Do you think it might be possible to see if you can get an earlier appointment with the rheumatologist or get on a waiting list in case of an appointment cancellation?
