Hi Coleen,
Welcome to the Board. I haven't done the stimulators, so can't give you any info there. Haven't had any of the "traditional" treatments actually, so I'll just say HI.
I've got in my feet and hands and arms. I'm sorry you're having such a rough time. It sounds really more painful than I face, and my heart goes out to you.
Has anyone suggested some vitamin therapies? I'm going to be starting on one, so I can't tell you first hand any information, but I've been finding amazing information about it. I didn't know that depletion of any ONE of a long list of nutrients can cause neuropathy. I about fell out of my chair! But I ramble.
Welcome to the board, hope you find some useful information here. Everyone is wonderful to talk to, vent to, or just get an encouraging word from.
