Symptoms:

In infants, the main sign is often irritability and inconsolable crying. Many infants and children with an acute ear infection have a fever or trouble sleeping. Tugging on the ear is not always a sign that the child has an ear infection.

Symptoms of an acute ear infection in older children or adults include:

• Ear pain or earache
• Fullness in the ear
• Feeling of general illness
• Vomiting
• Diarrhea
• Hearing loss in the affected ear

The ear infection may start shortly after having a cold. Sudden drainage of yellow or green fluid from the ear may mean a ruptured eardrum.

All acute ear infections include fluid behind the eardrum. You can use an electronic ear monitor, such as EarCheck, to detect this fluid at home. The device is available at pharmacies, but you still need to see your doctor to confirm any possible ear infection.

Signs and tests:

The health care provider will look inside the ears using an instrument called an otoscope. This may show:

• Areas of dullness or redness
• Air bubbles or fluid behind the eardrum
• Bloody fluid or pus inside the middle ear
• A hole (perforation) in the eardrum

A hearing test may be recommended if the person has a history of ear infections.
