Thank you for your quick reply. The thing is, the MRI also showed I have extensive degenerative disc disease at L5-S1. Would this also be present if it was a isthmic spondylolisthesis? Would the spondylolisthesis be the cause of the disc degeneration? I assumed since I had the disc degeneration this was the cause of the spondylolisthis making it a degenerative spondylolisthesis. At this point I just want to preserve what I have and hopefully get at least pain and zap free.
