@busterbrown How do you like them and do they help your feet? Just be careful at night I hold onto whatever is there to make it to bathroom my problem is balance my feet aren't as bad as others on here .

Hi Goils, I don't know who I was telling about this to this morning, but I have an Empi unit that is exactly like a TENS unit but the wires are crossed so it gives a cross current. Hope I got that right? My PT person recommended it and my insurance covered some of it. Here is a Google page and you can pick out the site you want for Empi. They probably sell standard TENS units as well. I thought the cross current worked significantly better: https://www.google.com/search Take good care, Sunnyflower
