i just finished my trial. first 3 days were horrible and tech called to see how i was. i am crying from more back pain plus the site of the implant. i was doing it wrong. after 4 days the tech came to my house and did some adjustment, but i only got relief from a high dose of electricity running thru my body. i did this for and hour each morning, afternoon, and evening. that cant be good for my body. my office visit post stimulator, i felt pressured to say it worked. i said its at a high dose to work for me. i worry about long term use effects on my body. i was walking over a mile aday before this implant. i could hardly go around the block. made me weak, worried about the wires breaking in my back. i wont say yes to the stimulator. it did not work for me, does not mean it will not work for you. lots of positive reviews out there.
