I have had two by two different practitioners. I would describe both as uncomfortable with painful moments, but they were an important diagnostic tool that identified my long fiber neuropathy.

While I am not lining up for one if my neuologist wanted to do a follow up compare to the one from a year and a half ago I would do so. He offered to slow down the pace if it I needed breaks between locations, though I do not recall the details of my first test as well.

I was sore afterward, but as stated it was a useful test despite that and as others have stated, there is the daily discomfort and pain dealt with. If the practitioner is well practiced I don't think it should cause long term issues, but of course results may vary.

Best of luck.
