A couple of weeks ago I started to have pain in my tailbone and hips. The pain gradually increased to the point that I can only sit in an office chair or dining table chair because it keeps me very erect. So, last week when I was charging my SCS, I thought that the batter had moved towards my spine but I blew it off. Over the next few days my battery moved from the outer left edge of my back to now right on top of my spine at the waist! I sam my PM SCS doc last week and he said he had never seen a battery move - my doc is one of the leaders in the SCS field and has done hundreds of the permanent implants! I'm having surgery day after tomorrow, Thursday, 5/3 and the doc is going to move the battery around to my abdomen. So, dealing with my "normal" pain levels have been made almost unbearable with the additional pain of the battery being jammed up against my spine. I believe if it could go between my spine and skin it would be over my left side now. Absolutely unbelievable! I cannot wait to have the corrective surgery - doc says if it is infected, he will remove the battery, sew me up and wait for the infection to clear and then cut me open again!
