Hi, First of all, in the 8 last years I have realized that when I doctor does not believe you there is no point in trying to convince him. It is better to find one who is open minded. I also took metropolol for 6 weeks and it made me faint more, depressive and had more BP swings. I am now on Propranolol with no side effects. Hormones can surely cause this. All my orthostatic hormones are out of wack when I stand up. I have been tested more than 12 times for my catecholamines and they are sky high. My BP is all over the place. From 220/170 to 0. This is cause by my hormones and my body not being able to adjust my BP. When I go upstairs I get chespain, I have to sit, take a break and get really syncopal.
