Hi Kris, I have had POTs forever, been a longtime member but seldom visit here any more. I aquired an autoimmune disorder almost three years ago have been taking prednisone almost that long at low doses. All I can can is that it's awful, it makes autonomic symptoms worse. I was also told by one of the experts office that autoimmune disorders will make pots worse, and believe me that is the case. I stand and my legs are so weak standing in line............ugh. I feel you pain but have no answers. Dotty
