Just had permanent scs Medtronic placed 12/15/2014 and will have my first post op visit 12/22/2014. I'm to learn how to charge battery at that time, but reading other post saw that you can have several programs. What kind of things should I be asking the rep when I see them, have no idea what this baby can do other than what they set up for me during the trial. Any suggestions, advice would be great.
