Swimmer's Ear Beyond the Pool: Causes and Cures

Swimmer's ear, medically known as acute otitis externa, is a common infection affecting the ear canal. While its name suggests a link to swimming, moisture from perspiration can also cause this painful condition. Approximately 10% of the U.S. population experiences swimmer's ear in their lifetime.

The infection arises when trapped moisture in the ear canal breaks the skin barrier, allowing bacteria like Pseudomonas aeruginosa to thrive. Symptoms typically appear within days and include intense pain, especially when the outer ear is pulled, along with itchiness, redness, swelling, and possible drainage.

Diagnosis involves a physical examination of the ear canal, which often appears red and swollen. Treatment commonly consists of eardrops containing antibiotics to kill bacteria and steroids to reduce swelling. For severe cases where the canal is too swollen, a physician may insert a wick to keep it open, with most infections resolving within ten days.

Preventive measures include keeping the ear canal dry and considering a mixture of rubbing alcohol and white vinegar for those prone to infections after water exposure. It's important to distinguish swimmer's ear from middle ear infections, which are more common in young children and often linked to respiratory illnesses.
