How do you get tested for this? Had a tilt table test but that doctor can’t give a true diagnosis but they felt it could be pots brought on by my nerve damage from a b12 deficiency that was left untreated for a while I saw a cardiologist they said they can’t really diagnose pots there but did give a heart monitor for 7 days Where do I go from there?.. A lot of my issues are from that b12 issue but pots could still be a big one if it’s from the nerve damage or even from when I had Covid I hear there’s pots induced by it
