I know you have gone through so much pain and nothing seems to ever help you, However, there is something I think just might.
I had the Medtronic Implant done for the bladder, no big deal and it worked great!!
But now they have the devices for pain. there are no drugs used, so you don't have to worry about that part. and there isn't any chat rooms or anything for the moderators to worry about.
Just straight information. I would recommend Medtronic for any reason, they are now coming out with one that is implanted in the back of the neck for people like my husband who is paralized on his left side and it actually allows them to use that part of thier body again. But that one is not out yet, however for pain, there is one and they DO WORK. they are very small and inserted into a fat pocket where you will never know it is there and a tiny wire is touching the problem nerves causing the pain.
It is the size of half a credit card and very thin, it never needs removed except maybe in 10+ years just to replace the battery.
You cannot feel it. Please read about it, almost every kind of surgeon can put one in, depending on the area being treated.
You can read all about it and get free information at: www.Medtronic.com
This might just be the thing that takes away all your pain, forever.
