What is Swimmer’s Ear?

Swimmer’s ear, medically known as otitis externa, is an infection of the ear canal—the passage between your eardrum and the outside of your ear. Most cases are caused by bacteria, though fungi can also be responsible.

The infection often develops when moisture becomes trapped in the ear canal, softening protective earwax and creating an environment where germs can thrive. Disrupting the natural protective layer of earwax—such as by using cotton swabs or other objects—can also make the ear canal more susceptible to infection.

Children and individuals who spend significant time in water are particularly prone to developing swimmer’s ear.

Swimmer’s Ear vs. Ear Infection

A common point of confusion is the difference between swimmer’s ear (otitis externa) and typical middle-ear infections (otitis media).

• Otitis externa (swimmer’s ear): Infection of the ear canal
• Otitis media: Infection behind the eardrum, in the middle ear

Both conditions require medical attention, as bacterial infections can worsen if left untreated.

Signs and Symptoms of Swimmer’s Ear

Swimmer’s ear is often easy to identify due to its hallmark list of symptoms, which include:

• Ear pain
• Swelling of the ear canal
• Feeling of fullness in the ear
• Itching in the ear canal
• Drainage from the ear
• Mild discomfort worsened by pulling on the outer ear or pressing on the tragus (the small bump in front of the ear canal)

Advanced infections may present with:

• Severe pain radiating to the head or neck
• Fever
• Blockage of the ear canal
• Swollen lymph nodes in the neck

These symptoms should never be ignored, as prompt treatment is necessary to prevent complications.

Diagnosing and Treating Swimmer’s Ear

Persistent or worsening ear pain is a signal to seek care. Diagnosis usually begins with a physical exam of the ear, and the ear canal may be cleaned if needed.

Treatment may include:

• Prescription ear drops containing antibiotics or steroids
• Oral antibiotics for more severe infections

When treated promptly, most cases of swimmer’s ear resolve without complications.
