@sharon44r You mentioned in an earlier post that you also have Hashimoto's. @lblauvel mentioned in another discussion having Hashimoto's and also being diagnosed with PMR, and may have some thoughts or suggestions - https://connect.mayoclinic.org/discussion/can-hashimotos-be-caused-by-pmr/.

I did have a lot more flareups my first time with PMR and I think for me it was a combination of things, sometimes triggered by diet, sometimes by overdoing exercise/activity the previous day or possibly tapering too fast or too much. If you haven't already seen it, you might find this discussion started by Mike @dadcue helpful:
