Had permanent SCS implant done 6/1/11 - for the last couple weeks, I've been experiencing discomfort/pain at the battery pack implantation site - (upper left buttock). I'm thinking it's just because I'm too skinny and there's no "cushion" around the battery pack. It's gotten very uncomfortable to sit and even lie down unless I sort of shift to the right to keep pressure off that side. I'm TRYING to eat more to gain back some of the weight I've lost over the last couple years (due to massive amounts of narcotic/opiate pain med consumption) - but not having a lot of luck yet. I've been weaning off meds since the implant, and I'm finally down to a more "reasonable" amount of pain meds - so hopefully I start getting my appetite back soon!! Has anybody else experienced this - and am I right in thinking it's just due to lack of fatty tissue???
