I have this only down in my lower back. My first back surgery they went in and tried to widen the spinal canals. Second surgery they had to fuse the L5-S1 and it's only a matter of time they say till I have to have the next vertebrate up fused as well. They said it could be anywhere from a couple years (it's been two and a half now) to 25 years, no way of knowing. I guess it all depends on how hard I am on my body. Anyhow, I'm hoping you get some good news from the doc you said just agreed to meet with you.
