this is a great answer! I was thinking the same thing. Where do you go to get more answers when someone thinks its just POTS when it could be any kind of dysautonomia?

I’m so sorry I didn’t see your comment until now. Did you have yours already? If so, how did it go? I almost passed out during mine. I was a bit worried that results would be skewed bc I was actually feeling okay that morning. But sure enough, the symptoms appeared within seconds of the tilt. My blood pressure dropped, HR increased, and I had blood pooling in my legs and feet.
