Prednisone to Kevzara back to Prednisone. ( Hope not )

PMR diagnosed High SED Rate I have been on prednisone for about two years starting at 15 mg and eventually figured out that my break even was 10 mg. I tried lowering my dose a few times and my pain severely increased especially below 7 mg : I have gained weight ( 20 lbs ) I started on Kevzara three months ago I complained to the doctor that my legs are very weak before I started kevzara . My thighs are very weak I need support to get up from the floor . She said I had prednisone myalgia . I am now down to 1 1/2 mg prednisone. I have pain in my knees ( never ever had knee pain ) weakness in my legs and neck pain ( I previously had neck pain and don’t know if it is related to being off prednisone and not related to PMR )
My sed rate is still one but my WBC is now 2.5 Down from 5.7 before Kevzara. It was 3.4 After 6 weeks on kevzara Doctor wants me to skip my next dose of Kevzara and take a blood test before the due date next Friday and one a week after the due date. My big fear is without prednisone and Kevzara I might have very severe pain.
It took a long time to lower my prednisone
What should I do next. Don’t want severe pain
By the way I have noticed anal leakage due to prednisone as commented on other summaries and think my slight incontinence has increased
