my daughter was giving a friend a piggy back ride and she tripped and fell and hit her head (front top-close to forehead), came home and said she had a bad headache and took 2 tylenol, she has vomited now also, and her head is still hurting real bad. Her eyes are fine-I checked with a flashlight, they respond normally, there is no bump on her head, I applied a cold pack to try to help with the pain...any suggestions.
