Thank you for your query on Healthcare Magic,
Children around this age can not describe their headache if present and they become cranky, fussy, irritable with crying and behaving aggressively some times.
Any family history of Migraine?
It could not be due to a brain tumor
as there may be abnormalities on physical neurological examination of your child.
This may be due to a simple headache or a migraine attack.
Nothing to worry as you are going to consult your Pediatrician
and he will evaluate accordingly if required with CT brain.
Hope I have answered your query.
