My daughter drives ones of the last reinforce steal frames chevy made. The trailblazer was ok with no damage. He said had a headache but didn't tell till he went to school. Took him to family doc and she ask us to take him to the ER. Er doc didn't want to do a ct scan because he doesn't like all the radiation on young kids. I think he did get a concussion. He came home and fell asleep. Says he has a small headache. Er doc said he may have one till tomorrow. Anyone have experience with concussion with kids age 13.
