There may be some bleeding, especially if you slid along it as you fell. There will also probably be bruising. You might feel dizzy, and will probably have a headache for a while. Most importantly, you could get a concussion. This depends on how hard you struck it. If you were very dehydrated at the time, there might be a greater risk of this, as well. If you continue to have symptoms for more than a day or two, you might want to get yourself checked out. You could also have someone do a eye response test. As they slowly bring the flashlight beam closer to your eye (do one at a time) the pupils of the eye should constrict (seem to shrink). If they remain the same or enlarge, then there was brain damage. This is helpful to let you know you do have a problem, but don't assume that if you passed the test that you do not have a problem.
