Hi Catfish and welcome to NT. I am so glad I saw your post. Just yest I had some Xrays for low back pain and the Dr told me that the L4-L5 discs have virtually nothing between them and they are bone on bone, which has formed a large bone spur. I have alot of lower back pain and also, b/c the discs are protruding, my R leg hurts... yada yada.
So thank you for your post.. It was really informative....
