I had a MRI done and got the results today. Can someone please tell me what this means.

1. Mild to moderate degenerative disc and endplate and
facet joint changes at L5- S1 with 1 cm. paracentral disc protrusion
with impingement of the left descending S1 nerve root at the level of
L5-S1. Small synovial cyst off the left facet joint also noted at
this level, which contributes to nerve root impingement at this
level.
