Key Takeaways
Swimmer’s ear, also called otitis externa, is an infection or inflammation of the outer ear canal. It usually develops when moisture becomes trapped in the ear, allowing bacteria or fungi to grow.
No. Swimmer’s ear is an infection and typically does not resolve without treatment. Without proper care, symptoms can worsen and the infection may spread to nearby tissues.
With appropriate treatment, most people begin to feel relief within 24–48 hours. Complete recovery usually occurs within 7 to 10 days, depending on the severity of the infection.
No. Swimmer’s ear is not contagious and cannot be passed from one person to another, even if multiple people swim in the same water.
Yes. Keeping water out of the ear canal is one of the most effective ways to prevent swimmer’s ear. Well‑fitting swimming earplugs, such as Bollsen Watersafe+ earplugs, can help reduce moisture exposure, especially for frequent swimmers or people prone to ear infections.
You should seek medical advice if ear pain persists, worsens, or is accompanied by drainage, swelling, or hearing changes. Early diagnosis and treatment help prevent complications and speed up recovery.
Swimmer’s ear, medically known as otitis externa, is a common and painful infection of the outer ear canal the passage that leads from the outside of the ear to the eardrum. Despite its name, swimmer’s ear doesn’t affect only swimmers. Anyone can develop it when moisture, irritation, or minor injury disrupts the natural defenses of the ear canal.
This guide explains what swimmer’s ear is, why it happens, how it’s treated, and how it can be prevented, using evidence‑based medical guidance and clear, practical language.
What Is Swimmer’s Ear?
Swimmer’s ear is an inflammation or infection of the outer ear canal. It most often develops when water remains trapped in the ear, creating a warm, moist environment where bacteria or fungi can grow.
Unlike middle ear infections, swimmer’s ear affects the skin lining of the ear canal, not the space behind the eardrum. This is why pain often worsens when the outer ear is touched or gently pulled.
What Causes Swimmer’s Ear?
The ear canal has natural protective mechanisms, including earwax (cerumen), which helps repel water and block germs. Swimmer’s ear occurs when these defenses are weakened.
Common causes include:
- Water trapped in the ear canal after swimming, bathing, or showering
- Frequent exposure to moisture, especially in warm or humid environments
- Removal of protective earwax
- Small scratches or irritation caused by cotton swabs, fingers, earbuds, or hearing aids
- Skin conditions such as eczema or psoriasis affecting the ear canal
- Swimming in natural bodies of water (lakes, rivers, oceans), where bacteria levels may be higher
When the skin barrier breaks down, bacteria (most commonly Pseudomonas aeruginosa or Staphylococcus aureus) or fungi can multiply and trigger infection.
Symptoms of Swimmer’s Ear
Symptoms can range from mild discomfort to significant pain and may worsen quickly if untreated.
Typical symptoms include:
- Ear pain, often severe and worse when touching the outer ear
- Itching inside the ear canal
- Redness and swelling of the outer ear or ear canal
- A feeling of fullness or blockage in the ear
- Drainage of clear, cloudy, or pus‑like fluid
- Reduced or muffled hearing
- Tender or swollen lymph nodes near the ear or neck
If symptoms persist or intensify, medical evaluation is important.
How Is Swimmer’s Ear Diagnosed?
Swimmer’s ear is usually diagnosed through a physical examination of the ear. A healthcare provider looks for redness, swelling, and drainage using an otoscope.
In most cases, no special tests are needed. If discharge appears unusual or the infection doesn’t respond to initial treatment, a sample may be taken to identify whether bacteria or fungi are involved.
Treatment Options
Swimmer’s ear does not usually resolve on its own. Prompt treatment helps relieve pain and prevents complications.
Treatment commonly includes:
- Prescription ear drops, which may contain:
- Antibiotics (to eliminate bacteria)
- Antifungals (if fungi are present)
- Corticosteroids (to reduce swelling and inflammation)
- Pain relief, such as acetaminophen or ibuprofen
- Ear cleaning by a healthcare professional if swelling or debris blocks the canal
- Temporary avoidance of swimming or water exposure during healing
With proper treatment, most people feel improvement within 48 hours and recover fully within 7–10 days.
Possible Complications
Complications are uncommon but can occur if swimmer’s ear is left untreated, including:
- Chronic or recurrent outer ear infections
- Spread of infection to nearby skin or cartilage
- Cellulitis or, in rare cases, deeper bone infection
Early treatment greatly reduces these risks.
How to Prevent Swimmer’s Ear
Prevention focuses on keeping the ear canal dry and protected.
Practical prevention tips include:
- Dry ears thoroughly after swimming or showering
- Tilt your head to let water drain out naturally
- Avoid inserting cotton swabs or other objects into the ear
- Keep earwax intact unless removal is advised by a professional
- Use well‑fitting earplugs for water, such as Bollsen Watersafe+ earplugs, if you are prone to infections or spend a lot of time in the water
- Avoid swimming in polluted or poor‑quality water
When to See a Doctor
Seek medical advice if you experience:
- Persistent or worsening ear pain
- Drainage from the ear
- Swelling around the ear or face
- Hearing changes that don’t improve
