Hi @pmrsuzie, Welcome to Connect. I'm sorry to hear that you have been dealing with PMR for 5 years. That is definitely the pits. My first time with PMR was 3 and half years and then six years later when my PMR came back, it lasted for 1 and half years. You mentioned low fat, low sodium, no caffeine diet. Here is some more diet related information that you might find helpful.

What helped me reduce my time on prednisone the second time around with PMR was eating healthier, eliminating as much sugar as possible 🙂 and adding more moderate daily exercise. I also take blood pressure meds so pretty much have eliminated any added salt and try to avoid high sodium foods.

Some people that have struggled to taper off of prednisone have been successful using the following tapering plan found on the HealthUnlocked website.

Do you keep a daily log of your pain levels and prednisone dosage?
