Overview
An ear infection (sometimes called acute otitis media) is an infection of the middle ear, the air-filled space behind the eardrum that contains the tiny vibrating bones of the ear. Children are more likely than adults to get ear infections.
Ear infection
In an ear infection, narrow tubes that run from the middle ear to high in the back of the throat (eustachian tubes) can become swollen and blocked. This can lead to mucus build-up in the middle ear. This mucus can become infected and cause ear infection symptoms.
Because ear infections often clear up on their own, treatment may begin with managing pain and monitoring the problem. Sometimes, antibiotics are used to clear the infection. Some people are prone to having multiple ear infections. This can cause hearing problems and other serious complications.

The onset of signs and symptoms of ear infection is usually rapid.
