I had a spinal fusion L4/5, unfortunately a piece of bone was chipped during the surgery and lodged in my L5 nerve. 7 years later after many pain injections and constant medication (I still take), I have just tried a Neural pain Stimulator implant. The trial went well and had a 60% reduction of pain. I have had the full implant done, but still not getting the same results as the trial. One thing the doctors cant really convey correctly is how intrusive the implanted battery is. It is near to your spine, about 2inches by 1 1/2 in wide, so you really do feel it while sleeping. I for some reason cannot sleep on my sides (definitely not the left one since bad operation), and now the right as well, so its back sleeping for me, I still wake from pain from laying on the battery too long, plus the site where the lead is anchored into your spine area. So while I am hopeful for better results, just wish I had been told about how BIG the battery was going to be. I am told by doctor its because I am on the leaner side build! Also not getting off meds, which is Lyrica and Methodone, so I know all about addiction! If I miss those meds by 3-4 hours I start getting withdrawal! My advice, is keep looking and trying new ideas for pain relief, BUT ask a LOT of questions!
