Thank you for your query.
If there has been no response to Tylenol
and she is still complaining of headache and dizziness
then she needs to be taken to the ER and a check-up done. Her blood pressure and her blood sugar needs to be examined which can be the likely cause of the problem in overweight
children though there can be a number of other reasons which a detailed history will be required.
I hope I have answered your query to your satisfaction.
Wishing your daughter an early recovery.
