Hello dear,
The symptoms as mentioned in your post suggest that your daughter might be having
Otitis media (infection/inflammation of the middle ear) most probably
Serous Otitis media.
In this condition, the middle ear cavity gets filled with serous fluid, resulting in bulging of tympanic membrane (eardrum) & interference with transmission of sound resulting in
conductive hearing loss.
Moreover, there is a connecting tract (known as Eustachian tube) between the middle ear & nasopharynx, obstruction of which can lead to sensation of blockage in ear & pain by un-equalisation of pressure.
Local examination of the ear along with tests like Audiometry &
Tympanometry will help in clinching the diagnosis.
Depending upon this, further steps for management can be taken.
So, it will be better to consult an
ENT specialist for further evaluation.
There is no need to worry, she will be fine.
Wishing her a Good Health.
Take care.
