Hi!
I had gone through your query and understand your concern.
A high temperature is always a concerning finding in a 3 years old child.
This temperature may due to a viral infection causing
gastroenteritis and in this case the fever can last for 2-3 days.
But since your kid's fever it is going on for two many days and it doesn't lower enough with
Ibuprofen (
Motrin) I can also think it might be a bacterial infection.
The major risk of
high fever is
Dehydration.So give plenty of fluids to your daughter and considering the fact that her fever doesn't respond to medication I suggest to take her to hospital.
The correct diagnosis is required to get the right treatment.
If the cause is a virus no specific treatment is needed,just rest,fluids,eating healthy and symptomatic treatment(treat fever).
If the cause is bacterial than an antibiotic is the treatment + fluids,rest.
The right cause can be found only in hospital and since she is to young child I don't suggest you to wait for doctor appointment.
Take her to hospital and meanwhile try to control her fever using Motrin.
Hope I was able to help you.
Wish a quick and complete recovery to your little girl.
