What is swimmer’s ear?
Swimmer’s ear (also called otitis externa) is an ear infection in your ear canal, the pathway between your outer ear and your middle ear. Swimmer’s ear may be a bacterial infection or fungal infection.
It’s called swimmer’s ear because many avid swimmers develop the condition at some point in their lives. But even people who rarely dunk their head in the pool, lake or ocean may develop swimmer’s ear. For example, skin conditions like psoriasis increase your risk of swimmer’s ear.
Left untreated, swimmer’s ear may affect your hearing, including causing hearing loss. Most of the time, treatment solves any hearing issues caused by swimmer’s ear. Healthcare providers treat swimmer’s ear with ear drops that eliminate the infection.
Will swimmer’s ear go away by itself?
No, it won’t. Swimmer’s ear is an infection in your ear canal that won’t go away unless it’s treated. Left untreated, a swimmer’s ear infection may spread to the base of your skull, your brain or your cranial nerves.
Symptoms and Causes
What are the symptoms?
Swimmer’s ear symptoms can be mild or severe, depending the infection in your ear. Symptoms may include:
- Ear pain: You may have an earache or notice ear pain if you pull or tug on your ear. Ear pain often gets worse if the underlying infection isn’t treated. Sometimes, the pain may spread from your ear to the side of your face.
- Itchiness inside of your ear.
- Drainage from your ear: This may be bad-smelling pus or yellow or yellow/green pus oozing from your ear.
- Blocked ear. This feels like something is in your ear or a sense of fullness in your ear.
- Redness and swelling in your outer ear.
- Temporary hearing loss or decreased hearing.
- Slight fever.
- Swollen lymph nodes around your ear or upper neck.
What causes swimmer’s ear?
Many things may cause swimmer’s ear, but the most common cause is activity that traps water in your ear canal. As bacteria and fungi thrive in warm, moist places, water pooling in your ear canal is the perfect environment for bacteria and fungi settle in, start multiplying and eventually cause infection.
Other causes include:
- Losing earwax: Earwax protects your ear canal from bacteria and fungi. You may lose earwax because there’s too much water in your ear or because you accidentally remove too much earwax when you clean your ears, irritating your ear canal’s delicate skin.
- Injuring your ear: You can damage your ear canal by sticking objects in your ear to try to remove earwax. (Think cotton swabs, pens, bobby pins or paper clips.) Probing your ear may push earwax and dirt even deeper into your ear canal
- Swimming in fresh water: You can develop swimmer’s ear from swimming in pools. But fresh water swimming — swimming in lakes, ponds, rivers, streams and oceans — increases your risk because fresh water may be polluted and contain more bacteria than you’d find in a pool.
- Skin conditions: Eczema or psoriasis in your ear canal increases your risk of developing swimmer’s ear.
- Chemicals: Chemicals in hairspray and hair dye that get into your ear canal may damage your ear and increase your risk of infection.
- Using earbuds or hearing aids: Hearing aids or earbuds that have been contaminated by dirt or other substances may cause an ear infection.
Diagnosis and Tests
How do healthcare providers diagnose swimmers ear?
A provider will examine your ears for redness, swelling or other signs of damage. If your ears are draining, providers may take a sample of the drainage to determine what caused the infection. Bacterial infections and fungal infections require different treatment.
Management and Treatment
How do healthcare providers treat swimmer’s ear?
Providers may prescribe ear drops that contain antibiotics and corticosteroids. They typically recommend over-the-counter pain medication to ease pain.
Can I prevent swimmers ear?
Yes, there are things you can do to prevent swimmer’s ear. Keeping your ears dry is the most effective way to prevent swimmer’s ear.
Dry your ears
Swimmer’s ear happens when there’s water trapped in your ear canal, creating a place for bacteria and fungi to multiply. Ways to dry your ears include:
- Wear clean earplugs when you swim or spend time in the water.
- Wear a shower cap when you shower.
- When you wash your hair, put cotton balls in your ears to reduce the amount of water in your ears.
- Use a dry towel to dry your ears after bathing, swimming or being in the water.
- Drain water from your ears by tipping your head from side to side and pulling your earlobe in different directions. The combination of tilting and pulling will help water drain from your ear canal.
- Use a hairdryer to dry out water in your ears. Use the lowest possible settings for the fan speed and heat level and hold the nozzle of the dryer several inches from your ears. That way, you won’t run the risk of burning your ear.
Protect your ears
- Ask a provider about drops to dry your ear canal after swimming or bathing. Ask if they recommend a homemade solution of vinegar and rubbing alcohol.
- Don’t stick anything into your ear canal.
- Don’t swim in polluted water.
- If you use earbuds or wear hearing aids, be sure to clean them before you put them in your ears. If you use hearing aids, ask your audiologist how to keep your hearing aids clean.
