Thank God for good programming! It has become quite apparent at 8 months post-permanent implant, my leads have scarred down off center, skewed to the right. With my favorite program - new as of 3 weeks ago, my rep and I determined that while laying on my left side, I have to set my Medtronic stim on 10.1 whereas when I'm laying on my right side, 8.7ish works. Stim when I'm sitting or walking is evenly balanced.
I still get great stim in all the right places, but rolling over in my sleep is awkward.
My rep did show me how just lowering the pulse width could pull a good program down out of my ribs so that it just stims low back, hips, and thighs to make it great (and save battery).
Just thought I'd share my continuing gratitude for this medical marvel.
