I have symptoms of SFN in my hands and feet and after a very very lengthy evaluation at Mayo Clinic it is considered idiopathic. I have tried the usual meds and for the usual reasons I have stopped taking all of them.

Acupuncture has been a God Send for me. It doesn't totally get rid of the pain, but it keeps it in the manageable zone. The down side is that I need to go weekly to stay on top of it, but can go 2-3 weeks if traveling.

The treatments have the usual needles placed all over the body, but my practitioner also uses the 7 star needle hammer, and it is the hammer that seems to be what works best. In fact, I recently had a treatment in China without the hammer and it did not compare to the treatments I get in MN with the hammer. It takes a bit getting used to, and it can hurt a bit, but in the big picture I couldn't be happier!!!!
