Hi Mike, I don't feel anything, in the way of electric shocks. However, when I was doing the trial I did have a time when I felt the electricity like holding an electric fence. I turned it off. I think the lead migrated. Nevro implant has a outside charging plate you place on the device and charge through the skin. It needs to be charged every day. I don't mind it. I keep a clock timer on to see how long it takes to charge. I take about 15 min. Twice a day. I have the device implant in my lower right back as I usually sleep on my left side. I'm at stage 3 neuropathy, which is constant fire and pain. This device kind of numbs the burning. I was using 2 canes to walk. I find it better to keep myself from falling down. I have not fallen. I wear a magnetic bracelet bought from Amazon for the purpose of me not falling. It may be an " only in your mind " but so far it has worked for me, so I wear it.
