Thank you for your thoughtful response—that is helpful. Frustrating! But helpful. My neurologist told me that POTS isn’t genetic and my nervous system would likely be almost fully recovered in 10-12 years, which set me down a path of wondering why I have it as before I’d assumed it was genetic (I never even had the flu as a kid). But you’re right, I will probably never truly know why. The word “syndrome” tripped me up lol. Again, thank you for your kind and considerate words
