I've had 2 occurrences of PMR. The first time it took me 3 and half years to taper off of prednisone and the PMR went into remission for 6 years. The second time with PMR, it took me 1 and half years to taper off of prednisone and the PMR went into remission again in 2018. I think lifestyle, diet and exercise play a part in helping to keep PMR in remission. It's just my opinion but I think you always live with the possibility that it will return.
