Mild degenerative changes in the lumbar spine are outlined level by level above. A disc bulge and facet disease approach the descending L5 nerve roots in the subarticular zone bilaterally at L4 to L5, and there is mild left greater than right foraminal narrowing at its level. The hypertrophied facet joint on the left at L5 to S1 exerts mass effect upon the descending left S1 nerve root, and extraforaminal disc protrusion on the left may abut the excited left L5 nerve root. The foraminal narrowing is also evident on the right at L2 to L3 and to a lesser degree on the left at this level and on the right at L3 to L4. What does this mean? I am now experiencing sciatic pain from the lower right back through my buttocks down to the right calf. Could it have progressed to this now presenting issue?
