I had the trial stimulator done a year and a half ago and it worked so well on all the pain I was experiencing in my back, legs and feet that I went ahead and had the permanent one installed. After a little adjustment, the back pain went away (all except for occasional stabbing pains in the area of the stimulator) but there was no improvement in my legs and feet. As a matter of fact the pain in my feet increased making walking extremely painful. I can't seem to get the doctor, his PA's or the stimulator adjustor to get me any relief. I am getting really upset.
