My child had an unexplained fall last night, that he cannot completely recollect. He slid off a wall while looking for a football. He scratched up his back and arm. When he landed, he walked a few feet and laid on the ground exhibiting some strange head and body movements. Once inside, he was emotionally upset, complained of dizziness and difficulty breathing. He has had no prior incidents. Although he looks pretty good right now, wondering if I should take him to emergency room for an evaluation.
