Dear Mudrat,
Continue to be your own advocate!!! YOU are the one who has to live with the pain, the implanted device, and the drugs in your system. If your doctor "never syncs," and gets defensive when you ask about it, maybe he doesn't actually know how to. Before making a final decision on changing doctors, you could call Medtronic Patient Services at (800) 510-6735, and get their input on the matter. They also have manuals available to download at their web site. Continue your own fact finding and internet research. Don't settle for a cursory response from a doctor who makes you feel like you are annoying them with your questions. You've entrusted the doctors and device makers to put "equipment" and powerful drugs in your body. You deserve answers that spell out your options and allow you to make informed decisions for yourself. I'm rooting for you!
