Swimmer's ear (otitis externa) is an infection of the outer ear canal, often after trapped water or over-cleaning. Learn how it differs from a middle ear infection, the tell-tale pain when you tug your ear, how it is treated, and how to keep your ears dry through the Indian monsoon.
Swimmer's ear, known medically as otitis externa, is an infection of the skin lining your outer ear canal, the tube that runs from the opening of your ear to the eardrum. The classic sign is pain when you tug on your ear or press the little flap at the front, along with itching, a blocked feeling, and sometimes a watery or smelly discharge. It is usually caused by water sitting in the canal, by humidity, or by scratching and over-cleaning the delicate skin. Most cases clear up with medicated ear drops from a doctor and by keeping the ear dry. It is not the same as a middle ear infection, and in India it turns up far more often during the monsoon and the sticky summer months.
What is otitis externa?
Otitis externa simply means inflammation or infection of the outer ear canal. That canal is lined with thin, sensitive skin and normally protects itself with a slightly acidic, water-repellent layer of earwax. When that protective layer is stripped away or the skin gets waterlogged, bacteria (and sometimes fungus) can move in and multiply. The result is a red, swollen, tender canal that can feel intensely itchy at first and then genuinely painful. Because the canal is a narrow tube surrounded by bone and cartilage, even a little swelling makes it feel tight, blocked and sore.
Otitis externa vs otitis media: knowing the difference
These two sound similar but they are different problems in different parts of the ear, and telling them apart helps you know what to do next. Otitis externa is an outer ear problem, in the canal you can reach with a finger. Otitis media is a middle ear infection, which sits behind the eardrum in an air-filled space you cannot touch, and it usually follows a cold rather than a swim.
- Otitis externa (outer ear): the pain is worse when you pull the ear or push on the flap at the front, the canal itches and may discharge, and it often follows swimming, bathing or humid weather.
- Otitis media (middle ear): the pain sits deeper, tugging the ear does not make it worse, it commonly comes after a cold or blocked nose, and fever is more likely, especially in children.
- One rough home clue: gently wiggle your outer ear. If that sharp tug of pain appears, it points more towards otitis externa than a middle ear infection.
This is only a guide, not a diagnosis. The two can overlap, and a doctor looking into your ear with a light can tell them apart in seconds. What matters is that you do not need to guess for long: if the ear is painful, get it looked at.
What causes swimmer's ear?
The name is a little misleading, because you do not have to be a swimmer to get it. Anything that leaves the canal wet, warm or scratched can set it off. The common triggers are:
- Trapped water after swimming, bathing or washing your hair, which softens the canal skin and washes away protective wax.
- Humidity and sweat, which is why cases climb during the Indian monsoon and the hot, sticky pre-monsoon weeks.
- Over-cleaning and cotton buds, which scrape off the natural wax barrier and leave tiny scratches for germs to enter.
- Scratching an itchy ear with a finger, key, hairpin, pen cap or matchstick, all of which injure the skin.
- Water from pools, ponds, rivers or contaminated water, which can carry more bacteria than clean tap water.
- Skin conditions such as eczema or psoriasis in the ear, and sometimes hearing aid or earphone use that keeps the canal warm and moist for long stretches.
Interestingly, having too little wax can be as much a problem as too much. Wax is not just dirt; it is your ear's own water-repellent, mildly antibacterial coating. This is one big reason we keep repeating that you should clean your ears safely and leave the canal alone, rather than digging into it.
Symptoms to watch for
Swimmer's ear usually starts mild and builds over a day or two. Early on it is often more itchy than painful, which tempts people to scratch and make it worse. Watch for:
- Pain when you tug or pull the outer ear, or press the small flap of cartilage at the front of the canal. This is the classic sign.
- Itching inside the ear canal, sometimes before any pain begins.
- A feeling of fullness or blockage, as if the ear is stuffed with cotton.
- Watery, cloudy, yellowish or foul-smelling discharge.
- Muffled or reduced hearing on that side while the canal is swollen or blocked.
- Redness and tenderness around the ear opening, and in worse cases some swelling that narrows the canal.
If the itch is the main problem and there is little pain, our guide to itchy ears and how to stop them may help you understand what is going on. But once real pain, discharge or swelling appear, treat it as an infection that needs a doctor's eye rather than home remedies.
How swimmer's ear is treated
The good news is that otitis externa usually responds well to treatment once the right drops are started. A doctor or ENT specialist will look into the canal, sometimes gently clean out debris so medicine can reach the skin, and prescribe medicated ear drops. Depending on what they find, these drops may contain an antibiotic, an antifungal, or an ingredient to calm inflammation. This is genuinely a case where the specific medicine matters, so please do not self-prescribe or reuse leftover drops from an old prescription.
Alongside the drops, the single most useful thing you can do is keep the ear dry while it heals. Water restarts the whole cycle. That means no swimming, and keeping water out during baths and hair washes, until the ear settles. Simple painkillers that you already use for a headache can ease the discomfort, and a warm (not hot) cloth held against the ear can be soothing. If your ear is discharging, do not plug it tightly; let it drain.
A quick, honest note on what we do and do not do. Prudent Hearing Solutions is an audiology clinic. We do not prescribe medicines or treat active infections; that is a job for your doctor or ENT. What we contribute is the hearing side: if an ear stays blocked or muffled after the infection clears, or if it keeps coming back, we can check whether your hearing has been affected. If you wear hearing aids and keep getting canal infections, we can also look at fit, venting and drying routines that reduce the trigger.
When to see a doctor
Mild itching that settles in a day is one thing, but a painful outer ear infection should be seen promptly, because it is easier to treat early and the right drops make a real difference. See a doctor without delay if you notice any of the following:
- Ear pain that is more than mild, or that is getting worse rather than better.
- Discharge from the ear, especially if it is coloured or smells bad.
- Swelling that closes the canal, or redness spreading to the outer ear or the skin around it.
- Fever, or feeling generally unwell along with the ear pain.
- Hearing that is noticeably reduced, or an ear that stays blocked after the pain settles.
- Symptoms in someone with diabetes or a weakened immune system, which deserve prompt attention because outer ear infections can occasionally become more serious in these cases.
If discharge or pain follows a cold, or the pain sits deeper and tugging the ear does not hurt, it may be a middle ear problem instead. And if you have been swimming in a pond or unclean water and the ear turns itchy, flaky and stubborn, it can sometimes be a fungal ear infection rather than a bacterial one, which is treated a little differently. Either way, a doctor looking into the ear settles the question quickly.
How to prevent swimmer's ear, especially in the monsoon
Prevention comes down to one idea: keep the canal dry and leave its natural wax alone. The Indian monsoon works against you here, with humidity that keeps ears damp for weeks, so a few small habits go a long way.
- Dry your ears gently after every swim, bath or hair wash. Tilt your head to each side to let water run out, and pat the outer ear with a towel. You can use a hairdryer on the lowest, coolest setting held a hand's width away.
- Do not use cotton buds inside the canal. They push wax and water deeper, scratch the skin, and remove the very barrier that protects you.
- Consider well-fitted swimming ear plugs if you swim often, or a snug swim cap that covers the ears.
- Try to keep pool, pond and river water out of your ears, and avoid swimming in water that looks dirty.
- Do not scratch inside an itchy ear with fingers, keys or pins. If itch is a recurring problem, get it checked rather than digging at it.
- In humid weather, take earphones and hearing aids out for spells so the canal can breathe and dry, and wipe hearing aids down as part of your routine.
For a broader, everyday routine that covers water, wax, itching and more, our guide to everyday ear care pulls the sensible habits together in one place. And if pain is what has brought you here, it is worth reading up on ear drops for pain in adults so you understand why the right drop for an outer ear infection has to be chosen by a doctor, not picked off a shelf.
"An outer ear infection is usually short-lived and very treatable. The trick is to keep the ear dry, leave the cotton buds in the drawer, and let a doctor choose the drops."
What to do next
If your ear is painful, discharging or blocked, see a doctor or ENT for the right medicated drops, and keep the ear dry while it heals. If the infection clears but your hearing still feels muffled, or if these infections keep coming back and you want to be sure your hearing has not been affected, that is where we come in.

Frequently asked questions
What is the classic sign of swimmer's ear?
The tell-tale sign of swimmer's ear (otitis externa) is pain when you tug or pull on your outer ear, or press the small flap of cartilage at the front of the canal. That movement stretches the inflamed canal skin and produces a sharp ache. It usually comes with itching, a blocked feeling, and sometimes a watery or smelly discharge. If wiggling the ear does not hurt and the pain sits deeper, it is more likely a middle ear problem instead.
How is swimmer's ear different from a middle ear infection?
Swimmer's ear (otitis externa) affects the outer ear canal, the tube you can reach, and hurts more when you tug the ear. A middle ear infection (otitis media) sits behind the eardrum in a space you cannot touch, usually follows a cold, and tugging the ear does not make it worse. Fever is more common with middle ear infections, especially in children. They are treated differently, so a doctor looking into the ear is the quickest way to tell which one you have.
Can swimmer's ear go away on its own?
A very mild, itchy irritation may settle if you keep the ear dry and stop scratching. But once there is real pain, discharge or swelling, it is an active infection that usually needs medicated ear drops chosen by a doctor. Leaving it can let the swelling and pain get worse and the canal block up. It is easier to treat early, so see a doctor promptly rather than waiting it out or reusing old drops from a previous prescription.
Why do I keep getting swimmer's ear in the monsoon?
India's monsoon and humid summer keep the ear canal damp for weeks at a time, and moisture softens the skin and washes away the protective wax that normally repels water and germs. Sweat, frequent bathing and swimming add to it. Using cotton buds or scratching an itchy ear makes it far more likely by stripping that barrier and scratching the skin. Drying your ears gently after every wash and leaving the canal alone are the two habits that break the cycle.
Should I use cotton buds to clean water out of my ear?
No. Cotton buds are one of the main causes of swimmer's ear. They push wax and water deeper, scratch the delicate canal skin, and remove the water-repellent wax layer that protects you, leaving the perfect conditions for infection. To clear water, tilt your head to each side to let it drain, pat the outer ear with a towel, and if needed use a hairdryer on its lowest, coolest setting held a hand's width away. Never poke anything into the canal.
Are ear plugs a good idea for swimmers?
Yes, well-fitted swimming ear plugs help keep water out of the canal and are worth trying if you swim often or are prone to outer ear infections. A snug swim cap that covers the ears adds protection too. The key is fit: plugs that are too loose let water seep in, and pushing hard plugs in can itself irritate the canal. Still dry your ears gently afterwards, because no plug is perfect, and avoid swimming in water that looks dirty.
