I noticed you mentioned in a different post that you're also taking methotrexate and soon to start injections. What injections will those be?

I don't have experience with the other medications for PMR, but echoing @johnbishop, that does sound like a relatively fast taper... My dad has PMR and if he is experiencing severe weakness and fatigue, it's a sure sign (given this has happened so many times over the last 14 months since diagnosis) he's having a flare and his prednisone dose was dropped too low.

He was diagnosed and started prednisone in May 2022, and his current prednisone dose is 6.25 mg. He takes LDN (low dose naltrexone) for fatigue, does daily gentle range of motion exercises, has done PT, and also meets with a therapist regularly. They practice relaxation techniques (i.e. breath practice).
