I am fairly new to this website and I am in the process of trying to figure out what is causing my POTS. My doctor is helping a little but I need to bring ideas to him. I was wondering if someone that knew how to do it could do a poll and see what issues caused everyone's POTS. I figure knowing what happens more than others will help me get those ruled out first. I know most people never get to know the cause, but I am getting to be pretty positive that it is because most doctors do not want to spend the time to look.
