PMR is "self-limiting"--meaning, yes, at some time it sets us free. I read that the average duration of disease is 5.9 years, but apparently there are two classes of PMR and some are lighter than others. Here is a short paragraph to read: https://pubmed.ncbi.nlm.nih.gov/4036982/.

Mary- This last spring, I would hsve described my pain as a 20 on a 10 point scale and was ready to cut off my arms or jump off a roof. For six to eight weeks, i have felt very good and am back to my old self. I am ecstatic that I can get in and out of the bathtub so easily as I love baths. I have recently gone to 5 mg and have had no problems titrating down. Late June my crp was down to about 10. Assume it is even lower now. The sed rate started at 20/high normal and in late June was 6. Will see what happens but I am very encouraged.
