Just had had a Medtronic unit put on 7-24-13 for lower back and leg pain. Programed unit to cover pain areas Rep. has 3 yrs programing. With in 3 hrs unit quite working on my back and still workrf on my legs and feet. Rep was to call on the 25th at 2pm to see how i was doing, i had to call them at 3pm with no call back from them. Told Rep what was going on i expected them to meet me to try to reprogram unit. All i was told was well the leads moved, i figured that out my self but with out trying to reprogram unit how am i to get any feel for how the unit is helping my real target pain area. What feedback can you give me, what have others experienced, Legs feel good but little help in back!
