Thank you for posting your query.
Most likely, your daughter does not have any internal brain injury
As of now, you can manage her headaches
with analgesics such as ibuprofen or diclofenac
However, if it persists, or if she gets vomiting, double vision
, etc, you should take her to ER and get a CT scan of the head done.
