I contracted PMR after my second COVID vaccination in March 2021 (? coincidence?) I have been taking 1 mg. prednisone for several months now and tried stopping twice, but did experience the pain moving from my shoulders to my back and neck, so I am once again taking 1 mg. I've also wondered if the reason I still have some deltoid pain at night was because I lifted too many heavy things during the day. (BTW, I only experienced pain while lying down and rarely felt anything when upright!) I walk 4 to 5 miles per day in my plant nursery business and attend a senior swim class twice a week and also use a stationary bike every other day (this is because of my hip pain, which they say is my osteoarthritis). I'm still in denial about that and keep wishing that this pain will dissipate once I'm in remission from the PMR. My thigh pain went away after my first dose of prednisone and has never returned, even when I tapered off. My pain is confined to my deltoides now and it is very mild, when I do feel it at night. Hope this helps you.
