Hi Karen,
I, too, have a herniation at L5-S1. I know the pain you are in. My whole lower back feels like it is broke into. The pain going down the back of my leg, feels like someone keeps kicking me.
I have several herniations but have never had surgery. That's a whole nother story.
I wish you all the best in finding a good doctor, whether it be a NS or OS. I would suggest looking on the internet and see if your doc is listed. There are alot of them listed and it tells alot about them.
Good luck,
Linda
