I know this is only anecdotal, but i “cured” my severe PMR with diet in 40 Days. My CRP went from 26. 3 to .6 in that time. I used the “Paddison Program” for Rheumatoid Arthritis, though I think any whole food plant based diet might have worked, so certainly worth a try, but you need to be strict with NO ADDED OIL. I have been 3 years vegan now with no PMR symptoms, no meds, and never felt better.
