Thank you for your query.
I can understand your concern. Following upper respiratory tract
infection, middle ear infection
can occur and it presents 3-5 days from the onset of the infection. Initially the ear drum can appear normal as in your daughter's case and later there can be middle ear infection. I suggest that you get her re-examined by the doctor to confirm or exclude middle ear infection by looking at the ear drum (tympanic membrane) once again.
In the mean time you can start her on a decongestant/cough
syrup and steam inhalation to give her relief from the pain.
I hope I have answered your query to your satisfaction.
