I saw the surgeon today, and he said the mri done a couple weeks ago showed some minor stenosis (narrowing of the spinal canal) and that was about it. So, the verdict is, on the 15th of March, I see his partner, to discuss having the discs at L-1/L-2 fused, along with having the stenosis addressed (again.) I just have to wait until I see the other surgeon and hope they can convince my insurance this has top be done. Otherwise I'll have a loose vertebra at the top of my lumbar spine.
Here is a link that kind of talks about the surgery, it's not gorey btw. The only part that bugged me is seeing the surgeon with a hammer & chisle !!
