I have a question and not sure where to put it. It is about type of pain. I founf I had two types. Pain when I wasn't using my muscles and pain when my muscles were under a load. Low Dose Naltrexone helped the non moving pain but not the one under a load. This pred addressed (when I finally got diagnosed.) Now my upper body is fine but my thigh muscles are painful- and stiff- under a load. Had EMG which was normal, so not nerves. PMR that only effects lower half of body? New disease? Any ideas?
