Welcome @andirae, It's not uncommon to have a lot of questions being fairly new to PMR and trying to taper off of prednisone. You are definitely not alone with the questions and the best thing you can do is learn as much as you can about the condition and how to manage the symptoms. I've had PMR twice and both times started at 20 mg prednisone. My first time took 3 and half years to taper off and I was in remission for about 6 years. The second time with PMR took me 1 and half years to taper off in the fall of 2018. So far it hasn't reared it's ugly head again but you never know. I did make some lifestyle changes which I think have helped but it remains to be seen. While you wait for others to respond, it might be helpful to read through a few other discussions on managing PMR symptoms and tapering off. Here's a search results link to the discussions and comments - https://connect.mayoclinic.org/search/?search=pmr+managing+symptoms.

It might help to keep a daily log with your symptoms when you get up in the morning plus your dosage of prednisone for the day. Do you keep a daily log?
