Welcome @debbieo123, Unfortunately PMR is not one of those 1 and done conditions. Once you start prednisone and the pain goes away quickly, that is pretty much how most doctors and rheumatologists know that you have PMR. Then your journey begins and you have to listen to your body while you are working on a plan or schedule to taper off of prednisone. If you taper too fast, the pain will come back. My first time with PMR took 3-1/2 years to taper off. The second time took 1-1/2 years to taper off. Here are a few references that explain the treatment.
