I would like to know how POTS was diagnosed for you. Was a tilt table test
Was all the possible conditions that can be associated with autonomic system dysfunction ruled out by blood and imaging tests ?
The symptoms which you describe here like memory loss
, tremors etc are actually confusing.
I would site an example here, suppose you had some early Parkinson
disease you would experience all of these symptoms. Because Parkinson disease like many other (at least 20 diseases) can have autonomic dysfunction and can look like POT.
And this amount of memory loss is never expected in POTS. Kindly reply with more details
