In 2004 I endured a botched attempt to implant of another brand of pain stimulator.  I had a most successful trial and was anxious for pain free days.  The surgeon botched that procedure.  Long recovery.  Then another Dr., another city, more shots, treatments, and finally another trial was scheduled.  This Dr. Said the ANS would be best for me.  During her attempt to place the leads, I felt everything she was doing.  The next day, the lead simply pulled out.  Dr decided to go proceed w/o a trial.  The reps were unable to program the device to do what I was told it would and could do.  Many, many times, reps from St Jude traveled to my town, meeting me at my  local Dr's office where we would attempt to program the device.  Never could.  Kept the device charged, kept trying, for more than four years.  The stimulator was removed Sept. 2012.  I requested that It be given to me.  I believe it was defective, and/or the leads were not placed correctly.   State regs. Would not allow.  After the removal, I began to have trouble walking. On Dec. 24, 2012, lost the use of my legs totally.  Jan. 8, 2013, another spinal cord surgery.  While I amazed the Dr's I survived that surgery, they were more surprised that I can walk.  Still wobble , but ever so thankful that I can walk.  I take no narcotics for pain and have not since a week after the Jan 8 surgery.
