My daughter is 8 year old and plays soccer.2 days ago, she was tripped during the game and landed on her face, causing a bloody nose. After getting the bleeding to stop she was ready to play again, and did fine the rest of the day. The next day she complained of headache, feeling shakey, dizzy at times,and lack of appetite, plus she had a low grade fever. With motrin, the fever reduces, and then she is able to eat a little something. Are her symptoms and the accident at soccer related?
