I'm wondering if part of the problem I'm having with my stim. is the settings. What exactly are you supposed to feel to have enough stim? Can you feel the buzzing and if so is it very light so you can hardly feel anything? Or is it supposed to be buzzing enough so you can feel the buzzing easily? It seems that when I can't feel the buzzing it wouldn't be keeping the pain away... yet when I can feel the buzzing it's so irritating. I think I'm missing a piece of the puzzle here with lack of info. Pretty much all I got was a video CD and booklet from medtronics that sang the praises of it, but didn't really get down to what you'd feel from it and what you should feel.
