I agree with Smith. Whatever advantages, big or small, are temporary.

I used it for the pain I had in my right foot, 20 years ago, long before I got PN. I used it for a mortons neuroma. It worked great, shrunk it, stopped pain....ONLY so long as I paid the bucks to do it 3 times a week. When I stopped, it grew back rapidly and pain returned. Finally did surgery.

Can't hurt to try, though I think it is temporary if any relief comes. The way it works is it disrupts the pain receptors.
