Okay, now I worried not only about having surgery, but now I'm worried about not having surgery. I just read about this woman who had bad neck pain and she went to an ortho who fit her with a cast and, after the MRI results showed she had nothing holding her neck vertabrae, was taken to emergency surgery. She was told that if she were to get rear-ended, she probably would not survive the impact. Scary stuff. I was wondering if this could be the case with my injuries, which showed the surgery I would need was a TLIF.
