Is there some kind of "POTS epidemic" going on at the moment? My sister told me that there are 3 teenaged girls on their street who have POTS. One of them is in a wheelchair and can no longer attend school.

I was diagnosed with CFS in the early 90s and had the NMH problem. It's much better now than it was then but still a problem.

Thanks for the info about alpha antagonistic and beta agonistic antibodies.
