Frustrated with Undiagnosed Symptoms

Others have already given the correct answer. You would need a referral to a cardiologist and an electrophysiologist. You will need a tilt table study and maybe a 30 day monitor.

Hyper andregenic POTS can cause high blood pressure when standing and all of those symptoms, they might try to dismiss you for having high blood pressure as they think POTS = low blood pressure but that's not true. Hyperandregenic POTS exists

I agree with getting a tilt table test. Usually with POTS your blood pressure lowers when you stand up and then the tachycardia kicks in because it's trying to get oxygenated blood back to your brain. I had sever episodes and paramedics used to have to take me to the ER all the time. Now that I get IV fluids, I still get dizzy and black out a bit but don't completely pass out... My cardiologist stinks and I need a new one so try to find one with Dysautonomia experience. Best wishes to get the correct diagnosis.

I'd ask for a Tilt Table test. It's hard to get a Dx bc Drs aren't very educated on it. Most don't know what POTS is, despite it not being an uncommon condition. Cardiology is a good way to go. If you want to see Neurology, look for a dysautonomia specialist. You can do this! You can also try a beta blocker with your current doctor. If you can, try to record your hr & bp everyday, 1x laying down, 1x sitting up, 1x standing, and any time you're having an episode. That data will help you & the doctors. I personally have POTS, Neurocardiogenic Syncope, and Panic Disorder, that all affect & trigger each other.
