Hurt Arm?

I was playing soccer today when someone infront of me shot the ball hard, it hit me around the forarm/hand it hurt for a couple of minutes but then I forgot aobut it and went on playing. Now when I bend my arm it hurts at the elbow and the inner forearm. At the elbow I feel a twinge in a nerve I think and at the forearm it's more of a muscle soreness. What do you think could have happened? What do you suggest I do?
