Thanks. When I decided to get the stimulator I figured getting cut open every 9 years for a battery was not a big deal. It is not really the surgery that I am concerned with it is the recovery...going to be cutting it close to that start of the drag racing photography stuff. The local track is supposedly going to reopen this year...and they are kinda counting on me being there.
I would weigh how I felt before the stimulator to after and gauge it by that. If you've gotten some good relief, it might be worth doing it again. Is there something that has an external battery pack?
