What Does My Spinal Scan Report Mean?

hi doc I was wondering in english what this means? L2-3 4.7 L 4-5 3.5 mm and L5S1 4.8mm and all of them say. Left paracentral disc protrusion combined with facet and ligamental flavum hypertrophy produces spinal canal narrowing, what dose this mean and will I need surgery to relieve my every day pain and my right leg and but always hurts
