question: I had an MRI scan done and don t understand the big words. At the L4-L5 there is a mild posterior broadbased disc bulge. This along with mild facet degenerative changes is enroaching on the neural foramina on both sides. At L5-S1 level, disc height is mildly reduced. There is diffuse posterior disc bulge along with mild facet degeneration. This is enroaching on the neural foramina on both sides. What does this all mean???
