Is it normal that i want to be active after getting hit by car?

Even after getting hit by a car while crossing the street, I still have the desire to be active. I got hit by a car yesterday. It was my first time. The experience was horrible. The doctor said I did not break any bone in my body. However, my body is extremely sore after that crazy impact. The car was going 45 miles per hour. I am also wondering if any activity is actually good for my body now.
