Hi Mere

I had the autonomic battery, including the thermoregulatory sweat test (flunked totally) the tilt test (passed out) valsalva (cardiac innervation issues), QSARTS (abnormal) any way, I had this done BEFORE they did the skin biopsy. The found a lot of abnormalities and that prompted them to do the skin biopsy.

Autonomic issues can result from other things than PN, but I think PN is usually the more common cause.

I did not get any answers as to WHY I have PN. I still don't have what I think is a satisfactory reason. The WHY question is a quandry that plagues most of us.
