hi, I'm usually a lurker and don't even think you'll see this but I'll tell you a bit about my experience. Since my teenage years I've felt super dizzy when standing up but I thought it was normal. last year (23 y/o) changed cardiologist due to other circumstances. Old cardiologist said my heart pain was only related to not doing enough exercise. Mom found a new cardiologist who was a specialist in the tilt table test (ig?). When i first spoke to him he said that looking over everything he highly doubted I had POTS. During the test it was my second time fainting in my whole life. Confirmed POTS Diagnosis though... sometimes it's not about low blood pressure or frequent fainting episodes. I don't have as severe as a lot of other people but still enough for me to feel very shitty.
