Kinda Weird Question? Elbow Surgery Questions.

Ashton

So I had elbow surgery and now there's a screw in my arm. So if I were to put a magnet up to it would it stick to my arm? Or would it do any damage? And would it be possible for a surgery that was in my elbow to affect my fingers, because ever since I've had some difficulty moving my ring finger and my pinkie? Just wondering!
