That's great to hear! Did you have the disc replaced? I have similar pain in L5-S1 due to a disc protrusion affecting the nerves in that region (either via impingement or, more likely, inflammation). Unfortunately, the surgeon I consulted said that surgery is rarely performed that far down the spine unless there's really serious symptoms.
In the meantime, I keep monitoring these studies on mesenchymal stem cells for disc regeneration, hoping one of them makes it to clinical trials :(
I had disc replacement as well as fusion, since C5-6 is likely in next few years. I got lucky because C-spine is much easier to operate than lumbar. They go in from front (neck) and do not need to touch the spinal cord. For lumbar, they have to.
