Hello @pmr52025, I would like to add my welcome to Connect along with @beauty44, @st1300 and others. I think anyone that is struggling to taper off of prednisone might find the following discussion helpful.
-- Hello How to Slowly and Safely Taper Off Prednisone but ... no set rules.

For both my occurrences of PMR I kept a daily journal of my level of pain when I woke up in the morning and my dose of prednisone for that day. It was recommended by my rheumatologist. When it was time to taper to the next lower level, I either went up half of my previous taper down or went to the next lower dose in my tapering schedule depending on my pain scale being less than 2 which was my acceptable level of pain that I could easily deal with.
