Hi, this morning my son hit his head with another kid from school and has a little red lump in the left side on the temple. He didnt went to the school nurse. When he got out of school he mentioned me it and that he has a little bit of head ache. I made him the pupils eye exam with a flashlight- ok, the balance exam- a little out of balance, he seems a little bit drowsy. He ate food after school, he is looking the tv and playing computer games. Should i worry about something? Should i bring him to the doctor or the hospital? Thanks for your help
