Down to 3 and a half pred a day, dropping a half every 2 months a suggested by rheumatologist. I have had PMR for three years now. However, I feel totally exhausted and have cold sweats all the time, even the slightest efforts result in perspiration over my brow, face, neck and chest. It is awful feeling so tired all the time. Any answers? Could this be a problem with my adrenals?
