For those who don't know, POTS is one form of orthostatic intolerance. There are also other kinds.
Folks with ME/CFS often have some form of orthostatic intolerance. It's one of the optional features in CDC diagnostic criteria, meaning it's common, but not required.
Roughly half of Long Covid patients meet ME/CFS diagnosis so no surprise that many of them have it, too.
