What Is Swimmer's Ear?
Swimmer's ear (otitis externa) is an infection of the outer ear canal — the tube that runs from the outer ear to the eardrum. It commonly occurs when water stays in the ear canal after swimming, creating a moist environment where bacteria can grow. It can also happen from scratching the ear canal or using cotton swabs.
Symptoms
- Ear pain — Often severe, worse when pulling on the outer ear
- Itching inside the ear canal
- Redness and swelling of the outer ear
- Drainage from the ear (may be clear, yellow, or pus-like)
- Decreased hearing from swelling
- Feeling of fullness in the ear
Treatment
- Antibiotic ear drops — Prescribed by your pediatrician, usually used for 7-10 days
- Pain management — Ibuprofen or acetaminophen as needed
- Keep the ear dry — No swimming, use earplugs or cotton ball with petroleum jelly for baths
- A wick may be placed if the ear canal is very swollen (to help drops reach the infection)
Prevention
- Dry ears thoroughly after swimming — tilt head to each side
- Use a low-heat hair dryer held at arm's length to dry the ear canal
- Consider preventive drops after swimming (ask your pediatrician)
- Never put cotton swabs inside the ear canal
- Use well-maintained, properly chlorinated swimming pools
When to Call the Pediatrician
- Ear pain, especially after swimming
- Drainage from the ear
- Symptoms don't improve after 2-3 days of treatment
- Fever or severe swelling
Key Takeaways
- Swimmer's ear is an outer ear canal infection, common after swimming
