An infection of the air-filled space behind the eardrum (the middle ear). An ear infection is usually caused by bacteria or viruses. Ear pain and fever are common symptoms. Less commonly, there may be drainage of fluid from the ear or hearing loss. Most ear infections go away on their own. Some require antibiotics.
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.
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.
