I have in the passed had the same results from a MRI reading. Please don't let it upset you so much. Dr.'s don't usually jump into surgery right away because this don't often fixed the problem. I have had 7 back surgeries, and if one would of fixed the problem, I wouldn't of had more. The narrowing means spinial stenosis. I have had it when it was called severe.

Here is what my back surgeon told me. We can operate, but the trouble is it usually you'll have more pain either up or down your spine after that. My one fusion turned out into 5 fusions, later on. Try what they suggest frist, then if that doesn't help, they will do surgery down the road. Surgery is not a quick fix! I wish you the best.
