Welcome @joycj, We husbands definitely need an encourager. Good for you for helping your husband with his tapering down on the prednisone. My first time around with PMR I spent the last six months of 3 and half years with PMR going back and forth between 1 mg and 1/2 mg until I was finally able to taper off. If it were me and I was at 2 mg and the pain came back, I would wait a day to see if the pain was still the same then bump it up half of the amount that I had previously went down. Mainly to see if I could the tapering going without going all the way back to the previous dose. We are all different so what works for one may or may not work for others but it might be worth a try.

Does your husband keep a daily log with his level of pain in the morning and the dose amount for that day?
