Wisco50, I think you are right on. I had the Medtronic traditional implanted last year. They the doctor and rep told me that is has worked for patients like me, who has chronic foot pain from 2 failed surgeries. I got slight relief from the trial but had a little back pain. So, I decided to have them take it out on August 2nd. The trial was brutal because of the pain back pain associated with the amount of tape used to hold the leads into place. So, it was really hard to determine if it reduced the foot pain. The doctor wrote in his report that I got 50% relief to justify putting in the permanent one. I should have asked to speak to a couple of his prior foot patients who the doctor claims got significant relief. I'm working with another doctor who does DRG. He gave me the names of 3 prior patients who had success with his DRG. Two had foot problems and one had a leg problem. They all recommend him and the DRG that he put into them. I hope you get some relief. God bless.
