Hi Mr.Debra, I do feel your difficulties you are going through since these many days.As per your quiry the numbness
may not completely go after such surgery. But definitely it must reduce drastically and you should feel much better immediately, at least with in a week you must feel the difference. Jerkings in the leg could be because of severe motor weakness in the leg muscles / problems at the nerve root
level. That need a through assessment and clinical examination/evaluation. Post operatively one follow up MRI
scan also can be helpfull. Meantime you can manage your self to some extent with regular Physiotherapy
.. wish you a good health ahead..
