I also had Covid for the first time in early Nov and my PMR symptoms were totally gone for about a week while I had it. Go figure. Subsequently have had the nagging postnasal drip cough since then and developed an ear infection which was treated with an antibiotic. I finished the antibiotic on the same day that I tapered from 7.5 to 5mg of predisone. Some of my symptoms reappeared and my rheumatologist suggested I go back to 7.5 but not before I had labs done. My ESR was elevated which confirmed her diagnosis of a flair. However when I told her of the ear infection she agreed that the elevated ESR could be from that. I am holding on 5mg with no significant increase in my PMR symptoms. I see her in a few days and will hope that the taper will continue successfully. I am going to suggest that instead of the 2.5 every three weeks that I have been doing be reduced to 1mg every 3 or 4 weeks. Fingers crossed.
