The worst thing someone can do in the event of an accident of slip and fall is to try and move someone, or trying to get up and move on their own. Take stock of your body parts, and try to decipher if there's any damage of big breaks - sometimes you won't even be able to tell from the initial shock, so it's best to wait for medical attention help. Go to the hospital if directed to do so. If you do not go to the hospital right away, visit a doctor within 48 hours.
