I have seen 3 different Medtronic Reps and the surgeon who put the unit in and they all agree that there is NOTHING wrong my unit! My surgeon even accused me of lying about the issues I'm having.. =( Sadly my case is Workman's Comp one, so the help I get is limited to what they feel I deserve. I'm trying to get my unit out and I think I will once again persue alternate options for treatment.
