Advice for first cardio visit and home OI test?

[Sushi]

I'm hanging on to hope that when the underlying cause is eliminated, even the POTS will vanish. Seems I've read of several people on forums who've had that very experience? What say you, @Sushi ?

Treating causes, for me this is pathogens, gut, immune system. On "good days" I no longer even need compression knee socks.
