Otitis externa

Doctors can usually diagnose swimmer's ear during an office visit. If your infection is advanced or persists, you might need further evaluation.

Initial testing

Your doctor will likely diagnose swimmer's ear based on symptoms you report, questions he or she asks, and an office examination. You probably won't need a lab test at your first visit. Your doctor's initial evaluation will usually include:

Examining your ear canal with a lighted instrument (otoscope). Your ear canal might appear red, swollen and scaly. There might be skin flakes or other debris in the ear canal.

Looking at your eardrum (tympanic membrane) to be sure it isn't torn or damaged. If the view of your eardrum is blocked, your doctor will clear your ear canal with a small suction device or an instrument with a tiny loop or scoop on the end.

The goal of treatment is to stop the infection and allow your ear canal to heal.

Cleaning

Cleaning your outer ear canal is necessary to help eardrops flow to all infected areas. Your doctor will use a suction device or ear curette to clean away discharge, clumps of earwax, flaky skin and other debris.

Medications for infection

For most cases of swimmer's ear, your doctor will prescribe eardrops that have some combination of the following ingredients, depending on the type and seriousness of your infection:

Acidic solution to help restore your ear's normal antibacterial environment

Steroid to reduce inflammation

Antibiotic to fight bacteria

Antifungal medication to fight infection caused by a fungus

Ask your doctor about the best method for taking your eardrops. Some ideas that may help you use eardrops include the following:

Reduce the discomfort of cool drops by holding the bottle in your hand for a few minutes to bring the temperature of the drops closer to body temperature.

Lie on your side with your infected ear up for a few minutes to help medication travel through the full length of your ear canal.

If possible, have someone help you put the drops in your ear.

To put drops in a child's or adult's ear, pull the ear up and back.
