LOUISVILLE, Ky. — Swimmer’s ear is an infection of the ear canal, the tubular opening that carries sounds from outside of the body to the eardrum. It can be caused by different types of bacteria or fungi.

Swimmer’s ear, or otitis externa, usually develops in ears that are exposed to moisture. People who get it often have been diving or swimming, which can bring the germs directly to the ear canal. Swimmer’s ear often happens during the summer months when lots of people are enjoying water activities. 

“Kids will be playing in the water this time of year,” said Dr. Mark Brockman Jr., a pediatrician with Norton Children’s Iroquois. “That moist environment that can occur in the ear canal is perfect place for specific bacteria to grow.

The main sign is severe ear pain that gets worse when the outside part of the ear is pulled or pressed on. Sometimes there is itching in the ear canal before the pain begins.

The outer ear might get red or swollen, and lymph nodes around the ear may get enlarged and tender. Sometimes, there’s a greenish-yellow discharge of pus from the ear opening. It can be hard to hear in the affected ear if pus or swelling of the ear canal begins to block passage of sound to the ear.

“If your child is experiencing that kind of pain or saying their ear hurts, it is best to see your doctor so they can have a look,” said Dr. Brockman.

If swimmer’s ear is treated with prescription ear drops, it is usually cured within 7 to 10 days. The pain should lessen within a few days of treatment. External otitis is not contagious, so you don’t have to limit your contact with friends as long as you’re feeling well enough to socialize.

Dr. Brockman Jr. advises parents to use a solution of half hydrogen peroxide and half water to help clean out ears rather than using q-tips. Drying your ears well with a clean towel after swimming, bathing, or showering can help prevent swimmer’s ear.
