@valb68 I have not taken a biologic, probably because it hasn't been needed for me. Shortly after my second round with PMR I started looking into lifestyle changes. I read a book by Dr. Terry Wahls – The Wahls Protocol. She has an amazing story about how diet helped her MS symptoms – https://terrywahls.com/about/about-terry-wahls/. So I have tried to focus on reducing or eliminating processed meats, sugar, fast food, and fried foods which I think helps with any autoimmune disease. Here's a link you might find helpful – What to eat if you have polymyalgia rheumatica: https://www.medicalnewstoday.com/articles/321683
Have you tried making any lifestyle changes to see if it helps with the PMR?
