I considered getting one of those.
My neurologist told me I would be wasting my money.
I did some research into it anyway.
Results were mixed, depending on what was causing the Neuropathy.
I would have gone ahead & got one if there had been any positive results from someone with the same problem as I have.
I also got the feeling a lot of the positive feedback was from people with a financial interest in the device.

earlyboy, could I ask the nature or cause of you wifes Neuropathy?
