I can relate exactly how you are feeling while on prednisone! There’s no magic formula for prednisone for me .If you are having problems with your dose of prednisone my advice to you would be speak to your rheumatologist and not change the dosage on your own!!! when you are not feeling well enough to do a certain activity do whatever is comfortable for you and if it’s not skip it for until you’re ready to do it!!! I also have OCD so I can understand where you’re coming from. PMR for me is very very disconcerting!!! My very best wishes to you!!!
