Yes, I have had it several times. The issue I had was every time I had the procedure done, it would be someone new hooking up the equipment. Some were good at it, but most were not. If it was done correctly and they truly hit the nerve, it worked, but most times they did not insert the needle in the exact spot it needed to be in. This is pretty much what my acupuncturist does with the stimulator attached to the needle and with his background, training, and knowledge he almost always gets it right.
