It took two fridays in a row 8 hours each day and they inserted 12 wires 4-up,8-down and it's not like you are out like a rock either, you have to keep telling them if it's in or out of position, I thought the surgery was overwelming , both times, for the stimulator.Trying to correct a nerve pain in my foot. Everytime I moved, The stimulation would shift as well. From my ass all down one leg then in my foot. I tried to get them re-programmed a couple of times, but It really did'nt help. Once I realized it wasnt for me I had it removed asap, and feeling alot better with out it.
keep in mind this is one persons experience. I definatly do not want anyone to think that because mine was'nt succesful that yours wont be. Everyone's condition it different.
good luck
