I had the same thing happen to me October 2020 and I'm still suffering and still trying to rule out everything else. The pain sucks. I finally took myself off prednisone because I grew a hump on my chest and I just could not lose weight and figured the extra weight was making me worse. Now I'm living on advil and tylenol. I feel like I'm 90 as every time I sit for awhile my knees lock up. Night is the worst as my arms, shoulders, and chest keep me awake. What works please?
