I had a laminectomy 2 years ago, between my knee and hip on left leg, I have burnng on the inside and numbness on the surface, will it go away?

How old R symptoms? If the leg symptoms were present before the laminectomy, I would not expect them to go away. They are caused by nerve irritation. If you had the numbness symptoms this long, they may not recover- it has been longer than 18 months. On the other hand, the burning probably will go away. If the symptoms are not related to the laminectomy, then I would have to give a different answer.
