Well the thing that jumps out at me the most is in bold -

[3. L5-S1: 4mm broad-based disc bulge in the right foraminal region ligamentum flavum thickening and facet arthropathy. There is no spinal canal stenosis. However, there is moderate right neural foraminal stenosis. Mass effect on the exiting right L5 nerve root is seen. There is mild left neural foraminal stenosis.

That is the one place where there is noted nerve involvement.
Of course the other issues can still cause pain & symptoms.
