BMR,

I use one because I blew out my back L4-L5-S1 in 2000. After my first operation I felt better than I had in about 15 years. I guess you could say I felt too good. Then I got stupid and too down a few trees and re-injured my back and I have been in constant pain. Next week is operations 5 and 6 to try a neurostimulator. BMR, I am really glad to see that your operation was sucessful. Now all you have to do is try to keep remimding yourself so you don't injure it again.
