Swimmer’s Ear: Causes, Symptoms, and When to See a Doctor

Summer means more time at the pool—but for many kids, it can also mean painful ear infections. Swimmer’s ear is one of the most common poolside problems parents face. Here’s how to spot it early and when to seek care.

What Is Swimmer’s Ear?

Swimmer’s ear, or otitis externa, is an infection of the outer ear canal. It’s often caused by water remaining in the ear after swimming, creating a warm, moist environment where bacteria or fungi can grow. Unlike a middle ear infection, which affects the space behind the eardrum, swimmer’s ear affects the external canal and is usually triggered by frequent exposure to water.

Why Are Kids More at Risk?

Children are more likely to spend long hours in the pool, lake, or ocean—especially in summer. They also may not dry their ears thoroughly or notice discomfort right away. The shape of kids' ear canals can also make it easier for water to get trapped. Tiny skin abrasions from cotton swabs, earbuds, or scratching can increase the risk of infection once bacteria enter.

Common Symptoms of Swimmer’s Ear

Most cases develop within a few days of water exposure. Watch for:

• Ear pain, especially when tugging on the earlobe
• Itchiness in the ear canal
• Redness or swelling around the outer ear
• Drainage of clear fluid or pus
• Muffled hearing or a feeling of fullness in the ear

If symptoms last more than a day or worsen, it’s time to see a doctor.

How Is Swimmer’s Ear Treated?

Your child’s doctor will likely prescribe antibiotic ear drops—sometimes combined with a steroid to reduce inflammation. The infection usually clears up in 7 to 10 days with proper treatment. Avoid getting the ear wet during recovery. Pain relievers like acetaminophen or ibuprofen can help with discomfort.

Tips to Prevent Swimmer’s Ear

• Dry ears thoroughly after swimming with a towel
• Tilt the head to help drain trapped water
• Avoid inserting cotton swabs or fingers into ears
• Use doctor-approved ear drops to dry ears after swim sessions (if prone to infections)
• Wear swim caps or ear plugs if needed
