I was hit by a car as a pedestrian, what are my legal rights?

It was my turn to walk across the cross walk. I was almost half way through the car walk and a black suburban SUV hit me. I flew and tumbled all the way into the street. The driver pulled his car to the side of the road and tried to get me off the road with the assistance of a witness. We were on the side walk and as the witness was calling the police we realized the guy who hit me got in his car and left. The police, fireman and ambulance showed up and immediately where checking my vitals and asking me questions. The driver that hit me returned. I suffered no major injuries, my knees were badly bruised and cut and received stitches, extreme soreness and pain all through out the left side of my body and a bruised rib. I've had to miss two days of work so far and have experienced trauma.
