For the record, I did take statins maybe for 3 or 4 years before getting PMR and I stopped partly because of perceived muscle pain. I also had a lot of diarrhea. Also for the record I was able to taper off Prednisone completely by the end of August 2019. I was originally diagnosed with PMR in August 2018 but probably had it for a couple of months before diagnosis. I believe that Prednisone caused me to have memory problems. This is somewhat improved since being off Prednisone.
