I seem to have the symptoms of hyperadregenic POTS (seems like too much adrenaline), but urine epinephrine, metanephrine and norepineprhine were all just out of range on the LOW side. Does anyone know what this could mean? Has anyone else had this problem? If so, what did you do that helped it? I was thinking of trying Clonidine, but I am not sure it will help because of the low epinephrine. Do you know of any other tests that determine hyperadgerneric? Thank you so much. I really appreciate your help.
