Hi ~ It says you have a disc protrusion at L4-5. It is pushing on the thecal sac, which is a membrane of dura matter that surrounds the spinal cord and the cauda equina, and is filled with spinal fluid. This bulge also contributes to spinal stenosis, which is narrowing of the spinal canal, and it also causes foramenal narrowing. The foramen is the hole which the nerves pass thru from the spinal cord.

I hope that helped a little bit. I doubt that at this point, you're a surgical candidate, but I'M NOT A DOCTOR, so you must ask your doctor about this. Be sure and get HIS opinion!!! Best of luck and keep us posted on what happens. Hugs, Lee
