Ear wax accounts for most ear discharges. However, they may also be caused by minor irritation or infection.
Ear wax serves as a protective lining for the ear canal.
Taking warm showers or washing the outside of the ears with a warm, moist washcloth usually helps prevent the build-up of wax. A ruptured eardrum in a child who has been complaining of ear pain is often demonstrated by a white, slightly bloody or yellow discharge from the ear. Dry crusted material on the child's pillow is often an indication of a ruptured eardrum. Don't get alarmed over a ruptured eardrum. Eardrum rupturing is the first sign of the healing process.
