An ear infection (acute otitis media) is most often a bacterial or viral infection that affects 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 infections frequently are painful because of inflammation and buildup of fluids in the middle ear.
Young children with otitis media may be irritable, fussy, or have problems feeding or sleeping. Older children may complain about pain and fullness in the ear (earache). Fever may be present in a child of any age. The buildup of pus within the middle ear causes pain and dampens the vibrations of the eardrum (so there is usually temporary hearing loss during the infection).

A warm compress- placing a warm, moist washcloth over the affected ear may lessen pain, Pain medication- acetaminophen (Tylenol, others) or ibuprofen (Motrin IB, Advil, others) to relieve pain, Eardrops- such as antipyrine-benzocaine-glycerin (Aurodex). Don't use benzocaine in children younger than age 2 without supervision from a health care professional, as this age group has been the most affected.
