I am a 43 year old female with severe back pain raidiating down left leg. recently had MRI results as follows:

At L4-5 there is somd disiccation of the disk as well as diffuse disk bulge and facet hypertrophy

At L5-S1, there is desicciation of disk. There is broad central disk herniation slightly more prominent left of midline displacing the left S1 root dorsally. There is also some facet and ligamentous overgrowth at this level.

Can anyone explain these results?
