After school today my 6 year old daughter is complaining of a headache, body aches, dizziness. She hardly had an appetite at dinner and she usually eats very well. She does not have a fever. She said she knocked her head on a shelf at school but I can not see any bruise or mark where she says it was bumped. She has rarely ever been dizzy. She went to sleep an hour early tonight after much complaining of dizziness.
