Welcome @papasrockyworld, It is definitely a great feeling when that first dose of prednisone kicks in and forces what I call Mr. Ugly into hiding. I'm hoping the pain will stay away when you start tapering off of prednisone. Many of us struggle with tapering and trying to taper too much and too fast to get off of prednisone. You mentioned it has also given you a giant appetite for food. I think that may be one of the warning flags for some of us with the weight gain side effect of prednisone.

There are a couple of other discussions you might find helpful in your PMR journey:

--- When and How to Taper Prednisone: https://connect.mayoclinic.org/discussion/when-and-how-to-taper-prednisone/

One suggestion that I think could help is to keep a daily log with your level of pain/aches when you get up in the morning along with your dosage of prednisone for that day. Has your rheumatologist suggested a tapering schedule for you?
