Ear Infections

Ear infections occur when a cold, throat infection, or allergy attack causes fluid to become trapped in the middle ear. Mostly affecting children, symptoms may include earaches and thick, yellow fluid coming from the ears.

Understanding Ear Infections -- the Basics

An ear infection, or otitis media, is the most common cause of earaches. Although this condition is a frequent cause of infant distress and is often associated with children, it can also affect adults.

The infection in the middle ear (the space behind the eardrum where tiny bones pick up vibrations and pass them along to the inner ear) very often accompanies a common cold, the flu, or other types of respiratory infections. This is because the middle ear is connected to the upper respiratory tract by a tiny channel known as the Eustachian tube. Germs that are growing in the nose or sinus cavities can climb up the Eustachian tube and enter the middle ear to start growing.
