- Ear Infections-Cause. Middle ear infections are caused by bacteria and viruses. Swelling from an upper respiratory infection or allergy can block the eustachian tubes, which connect the middle ears to the throat. So air can't reach the middle ear. This creates a vacuum and suction, which pulls fluid and germs from the nose and throat into the middle ear. The swollen tube prevents this fluid from draining. The fluid is a perfect breeding ground for bacteria or viruses to grow into an ear infection.

- Ear infections are often termed otitis media (middle ear infection) or otitis interna (inner ear infection) and can be caused by the presence of bacteria containing particles, viruses and mucus becoming blocked or trapped in the ear cavities.

Medical Definition of Ear infection, middle (acute) The buildup of pus within the middle ear causes pain and dampens the vibrations of the eardrum (so there is usually transient hearing loss during the infection). Severe ear infections may cause the eardrum to rupture. The pus then drains from the middle ear into the ear canal.

Pain will get worse when you press on the bone behind the ear. This infection is rare and usually occurs 10 to 14 days after a middle ear infection. Headache with severe stiff neck, irritability, confusion, and excessive sleepiness may be caused by an infection of the lining of the brain (meningitis).
