Swimmer's Ear

Swimmer's ear is inflammation, irritation, or infection of the outer ear and ear canal. The medical term for swimmer's ear is otitis externa.

Causes

Swimmer's ear is fairly common, especially among teenagers and young adults.

Causes of swimmer's ear include:

  • Swimming in polluted water
  • Scratching the ear or inside the ear
  • Object stuck in the ear

Trying to clean wax from the ear canal, especially with cotton swabs or small objects, can irritate or damage the skin.

Swimmer's ear is occasionally associated with middle ear infection (otitis media) or upper respiratory infections such as colds. Moisture in the ear makes the ear more prone to infection from water-loving bacteria such as pseudomonas. Other bacteria, and rarely, fungi, can also cause infection.

Symptoms

  • Drainage from the ear -- yellow, yellow-green, pus-like, or foul smelling
  • Ear pain -- may worsen when pulling the outer ear
  • Itching of the ear or ear canal

Exams and Tests

The doctor will perform a physical exam, which includes looking inside the ears. The ear, including the ear canal, appears red and swollen. The skin inside the ear canal may be scaly or shedding.

Touching or moving the outer ear increases the pain. The eardrum may be difficult for the doctor to see because of a swelling in the outer ear.

The doctor may take a sample of fluid from the ear and send it to a lab so any bacteria or fungus can be identified.

Treatment

The goal of treatment is to cure the infection. Medicines may include:

  • Ear drops containing antibiotics
  • Corticosteroids to reduce itching and inflammation

The ear canal should be cleaned of drainage. This allows the medicines to work better.

Four or five ear drops should be used at a time, so that the medicine can get into the end of the ear canal. If the ear canal is very swollen, a wick may be applied in the ear to allow the drops to travel to the end of the canal.

Analgesics may be used if the pain is severe. Placing something warm against the ears may reduce pain.

Prevention

Protect ears from further damage.

  • Do not scratch the ears or insert cotton swabs or other objects in the ears.
  • Keep ears clean and dry, and do not let water enter the ears when showering, shampooing, or bathing.
  • Dry the ear thoroughly after exposure to moisture.
  • Avoid swimming in polluted water.
  • Use earplugs when swimming.
  • Consider mixing 1 drop of alcohol with 1 drop of white vinegar and placing the mixture into the ears after they get wet. The alcohol and acid in the vinegar help prevent bacterial growth.
