Are you talking about the Syn-One Skin biopsy test or something else? I’ve been told by some good doctors I don’t have it, but I think I do, nothing else would explain the diverse symptoms I have including orthostatic hypotension. I have plans to get the Syn-One test, but then again, it’s not without error. So here we are. Does your husband have any autonomic symptoms like heart rate, erratic B/P, sweating or not sweating? It’s a lot to deal with, isn’t it?
