i had a MRI and it says L4-L5: there is a moderate broad based central disc protrusion that effaces the ventral aspect of the thecal sac causing mild central thecal sac narrowing and mild subarticular zone effacement bilaterally. There is modertate faucet ligament flavum hypertrophy with patent neural foramina. what does that mean? my doctor is refering me to a neurosurgeon. Does this really require surgery? Am I doing damage by continuing to work? I am a housekeeper and it is very physical and the thing that causes me the most pain. I already did and continue to do physical thereapy since september
