Are there actual discs at the S2 and S3 levels? I know there are nerve roots there, but from the looks of all the images of my back, I can't see any space for discs. I'm now fused from L3/4 to S1. I've been told to be careful with bending, lifting, twisting (BLT) because I would have a high possibility of rupturing the disc at L2/3. Should I worry about the lower levels too?
3 level spinal fusion, L3/4, L4/5, L5/S1, November 2008. Stiff, but I can walk.
