You haunt mentioned if you had a swelling at the sight of injury, wether you felt dizzy at the moment. Do feel nausea tic.?.well, if no such symptoms present, then chill. You have nothing to worry. If you are still experiencing mild pain at the sight of injury, ice pack fomentation should help you. If pain little more, take any analgesic at the time of sleep. If yet any doubt, then go ahead and get an X-ray skull or CT-scan, plain(head), done.this will clear all your doubts, and you can peacefully enjoy your trip to Ohio. So take care, best of journey. </s>
