Will numbness after hand surgery go away?

I had hand surgery on Friday. Today is Thursday. I had a removal of a benign tumor in my ring finger and had a hand cast put on till Wednesday. After the surgery, I have noticed that my ring finger, my pointer finger and the inside of my thumb are all numb. I am very worried that I may have nerve damage. Could this be permanent or will this go away in time? Has anyone else experience this when they had hand surgery done? Will the numbness go away?? I am concerned.
