My husband has just had discectomy surgery on his L4 - L5 disc which he hurt at work shoveling concrete. He hasn't had any instant relief as I think he was expecting. He is still having pain in his leg. I have read that due to the nerve being compressed for so long it can take a while for the nerve to heal and you can get sort of phantom pains while it takes time to heal. Just after some success stories where pain has slowly gone even though the pain is staying the same at the moment.
