when I had painful neuropathy (I don't anymore, I have numbness and motor loss) I tried a tens unit and it didn't really do much for me. It might have lowered the pain from an 10 to an 8, but that just wasn't significant enough for me to be worth the hassel.

I was able to hire one before buying - so, I didn't buy of course - but see if you are able to do this. Of course if you can get it on insurance that is something else, but that wasn't an option for me.
