Wow Renee your info is so complete and I am sure very helpful for people. I feel so silly when I read what so many people are going thru compared to my pain. The STEMWAVE PNS system that I will be getting, hopefully in a week or so, is 2 leads set around the femoral nerve in my thigh , with a EXTERIOR battery worn on my thigh and a remote control I can carry in my pocket. I get 3 batteries so I can always have back up charged.I wish you all well and keep searching there are answers out there PEACE
