question: Our 5 year old son bumped his head on a metal bar above an 8 foot slide and lost his balance and fell off slide onto sand. He fell onto his side. He cried for 5-10 minutes. His eyes seem to be dilating fine. He is not in pain to the touch on his side or back. He was alert, able to see and speak clearly, After about an hour after the incident, He said he said he has a stomach ache, but went to bed easily as it was 2 hrs past bedtime. There are no bumps on his head. He is not complaining of other pain. We are out of town on vacation in a remote area. We plan to wake him once tonight to make certain that he is able to be woken fairly easily. Are there other symptoms we should keep an eye out for? Are there possible injuries we should look out for? We plan to call our pediatrician in the morning.
