Hello,
Does your child have any rash or red splotches on her body? She seems to have 
photophobia as she has pain on seeing light. 
This is a significant problem suggesting a sinusitis or meningitis-like symptom. does she have stiffness in the neck vomiting?
Has she been immunized for her age? There is a significant cough with 
chest pain suggesting of a 
respiratory tract infection.
You have mentioned she is on some antibiotics but there are no details here.
I want to know her activity pattern between fever or so-called interfebrile phase, the number of times she gets a fever in the day, her appetite activity, urine frequency etc.
Since the fever is persistent I would like to get her blood counts like total and differential counts, x-ray chest 
blood culture and CSF. 
I would like to rule out meningitis and sinusitis by getting a C T scan of the head and a 
lumbar puncture after she is examined by your local paediatrician.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr ASHWIN BALIGA, Pediatrician
