Swimmer's Ear vs. a Regular Ear Infection: How Parents Can Tell the Difference

Your child climbs out of the pool happy and waterlogged, and by bedtime they’re tugging at one ear and fighting tears. Now you’re left guessing: Is this swimmer’s ear or a regular ear infection? The two feel almost identical to a child, but they’re different problems that need different care, and the treatment that fixes one does nothing for the other. There are a few telling signs that can point you in the right direction.

Swimmer's Ear vs. Ear Infection: The Key Difference

The single most important difference is location. Think of the eardrum as a wall:

• Swimmer’s ear (otitis externa) is an infection of the outer ear canal: the tube between the outside world and the eardrum. It develops when water gets trapped in the canal after swimming or bathing, softening the skin and washing away protective earwax so bacteria can grow. It’s an “outside the eardrum” problem.

• A middle ear infection (otitis media) — • what most parents mean by a “regular” ear infection, happens behind the eardrum. It usually follows a cold or other upper respiratory illness. Congestion swells the eustachian tube, the small passage that connects the middle ear to the back of the nose and throat. That tube normally drains fluid and keeps pressure balanced (it’s what makes your ears “pop”), so when it’s blocked, fluid gets trapped in the middle ear and can become infected. It’s an “inside the eardrum” problem, and pool water can’t cause it. Water in the ear canal never reaches the middle ear when the eardrum is intact.

Because the causes differ, timing tells a story. Ear pain a day or two after lots of water time points toward swimmer’s ear. Ear pain during or just after a congested, runny-nose illness points toward a middle ear infection, even in summer, and even if your child has also been swimming.

Both are common in children. Middle ear infections peak in babies and toddlers, whose eustachian tubes are shorter and more horizontal, as the AAP’s parent guide to ear infections explains, while swimmer’s ear is most common in school-age kids who spend long stretches in the water.

Swimmer's Ear Symptoms in Kids

Ear pain after swimming is the classic clue, but here’s what our clinicians look for—and what you can check at home:

• Pain when the outer ear is touched or moved. This is the hallmark. Gently tug your child’s earlobe or press the small cartilage bump in front of the ear canal (the tragus). With swimmer’s ear, this simple “tug test” typically causes real pain; with a middle ear infection, it usually doesn’t.

• Itching inside the ear canal, often the very first symptom before pain sets in

• Redness and swelling of the ear canal opening — In more advanced cases, the canal can swell nearly shut, and the outer ear may look red or puffy.

• Drainage that may be clear at first, then cloudy or yellowish

• Muffled hearing if swelling or debris blocks the canal

• Little or no fever — Swimmer’s ear usually doesn’t cause a significant fever. Chewing may hurt, but cold symptoms are absent.

Pain from a swimmer's ear can escalate quickly and become surprisingly severe, so don’t be alarmed if a child who was fine at bedtime is miserable by morning — but do have the ear examined.

Middle Ear Infection Symptoms in Kids

A middle ear infection tends to look and feel different. Common earache and ear infection symptoms include

• Deep ear pain that often worsens when your child lies down. This is why these infections so often announce themselves at bedtime or overnight. Touching or wiggling the outer ear usually does not make it worse.

• A recent or current cold. Runny nose, congestion, and cough in the days beforehand are the classic setup.

• Fever, which is common with middle ear infections and uncommon with swimmer’s ear.

• Trouble sleeping, fussiness, and reduced appetite — sucking and swallowing change ear pressure and can hurt.

• Muffled hearing or not responding to quiet sounds, from fluid behind the eardrum.

• Sudden drainage with relief of pain, which can mean the eardrum has ruptured under pressure. This sounds scary, but it usually heals quickly without long-term complications; the ear should still be examined promptly.

When Your Child Can't Say Where It Hurts

Babies, toddlers, and children with speech delays can’t always tell you their ear hurts — and “my ear hurts” from a 2-year-old can sometimes mean a sore throat, a tooth, or nothing at all. Here’s how to investigate like a clinician:

What to watch for

• Pulling, rubbing, or batting at one ear — especially paired with crying, fever, or a cold

• Crying more when lying flat, and settling when held upright (suggests middle ear pressure)

• Crying or flinching when the ear is touched — during hair washing, when putting on a shirt, or with a gentle tug test (suggests swimmer’s ear)

• Refusing to nurse, bottle-feed, or chew on one side

• New clumsiness or balance trouble, not turning toward sounds, or turning the TV up

• Visible drainage or a bad smell from one ear

Questions that work better than “where does it hurt?”

Young children answer concrete, either/or questions far better than open-ended ones. Try:

• “Show me with one finger where the owie is.” (Pointing is easier than describing.)

• “Does it hurt when Mommy/Daddy presses here?” — gently touch the outer ear, then the jaw, then the throat, and watch the reaction to each.

• “Does it hurt more when you lie down or when you sit up?”

• “Is it an itchy feeling or a hurting feeling?” (Itching points toward swimmer’s ear.)

• “Does it hurt when you eat your crackers?” (Chewing pain occurs with both, but paired with the tug test it helps localize the problem.)

Whatever the answers, a home assessment is a starting point, not a diagnosis. Only a clinician looking in the ear with an otoscope can confirm if either condition is present.

Swimmer's Ear Treatment and How Long It Lasts

Swimmer’s ear is treated with prescription antibiotic ear drops, sometimes combined with a steroid to calm swelling. Drops treat the infected canal directly and work faster than oral antibiotics for this condition, which is why the clinical practice guideline for acute otitis externa recommends them as first-line treatment. Most children feel noticeably better within a couple of days, and the infection typically clears in 7–10 days. Keep the ear dry during treatment (no swimming until your clinician gives the all-clear), and finish the full course of ear drops even after symptoms fade. Avoid headphones and earbuds until symptoms resolve, and disinfect them before reusing.

Middle ear infections are managed differently. Many are viral or resolve on their own, so depending on your child’s age, temperature, and severity of symptoms, your clinician may recommend watchful waiting with good pain control for 48–72 hours, an approach supported by the AAP’s acute otitis media guideline, or prescribe oral antibiotics. Ear drops can’t treat a middle ear infection because the eardrum blocks them, which is exactly why the right diagnosis matters before anything goes in the ear.

For either condition, age- and weight-appropriate acetaminophen or ibuprofen is the workhorse for comfort.

A warm (not hot) compress against the ear can also soothe pain. Don’t be surprised if you notice a little more drainage afterward: warmth can soften wax and help fluid already in the canal drain. Two things to avoid: never put drops, including leftover or homemade drops, into an ear that’s draining or that may have a ruptured eardrum, and never use cotton swabs inside the canal.

How to Prevent Swimmers Ear

You can’t prevent every middle ear infection (though staying current on vaccines, avoiding secondhand smoke, and good hand hygiene all help). Swimmer’s ear, though, is largely preventable:

• Dry the ears after every swim and bath. Towel the outer ear, then have your child tilt their head to each side so water drains out.

• Use a hair dryer on the lowest, coolest setting, held about a foot away, to gently dry stubborn moisture.

• Ask your clinician about over-the-counter drying drops (usually a diluted alcohol/acetic acid mix) after swimming. These are helpful for kids who get swimmer’s ear repeatedly, but never for a child with ear tubes or a history of a perforated eardrum.

• Skip the cotton swabs. Earwax is protective; swabbing strips it away and scratches the canal, opening the door to infection.

• Consider swim earplugs or a snug swim cap for frequent swimmers or kids prone to repeat episodes.

• Choose well-maintained pools when you can — poorly chlorinated water and hot tubs carry more of the bacteria that cause swimmer’s ear.

When to Call the Pediatrician About Ear Pain

Trust your instincts — ear pain that has your child miserable deserves a look. Call us the same day, or use our same-day sick visits, if your child has:

• Ear pain lasting more than a day, or severe pain at any point

• Any drainage, blood, or pus from the ear

• Fever along with ear pain — especially 102.2°F (39°C) or higher

• Noticeable hearing changes, or symptoms that aren’t improving after 2–3 days of treatment

If your child is an infant under 6 months, call us for any signs of ear pain or fever.

Seek urgent care right away for redness, swelling, or tenderness of the skin behind the ear; an ear that appears to be pushed forward; a stiff neck; a very ill or unusually drowsy child; or facial weakness. These are uncommon, but they can signal infection spreading beyond the ear.

Not sure whether it’s worth a trip? A pediatric video visit is often a quick way to talk it through — though a definitive ear diagnosis still requires an in-person look with an otoscope.
