The sweat test was awful. You basically wear your underwear, lie down in what amounts to a glass oven, then they spread sand all over your and you sit still for an hour and bake. Then they take a picture at the end.

And purple means sweat, yellow means no sweat. It shows what sweat glands activated by the autonomic nervous system. Then you have to shower it off and it takes forever.

They were very professional about it though, it was a nurse, a doc, and technician. I guess they were doing multiple tests at the same time, but I never saw other people doing it. Which was a relief I didn’t really want to see other purple people
