I have a Medtronic Spinal Cord Stimulator. Unfortunately they were only able to insert one wire down my spine instead of two. This is due to my spinal cord injury. For a year I was able to walk really well and my pain was much less. After the year, I was suddenly not able to walk easily and my pain increased. I tried different programs, but nothing helped. The doctor now refuses to remove the battery. I would not recommend a S.C.S.
