What are symptoms of swimmer's ear?

  • The first symptom of infection is that the ear will feel full, and it may itch.
  • Next, the ear canal will swell, and ear drainage will follow.
  • At this stage the ear will be very painful, especially with movement of the outside portion of the ear. The ear canal can swell shut, and the side of the face can become swollen.
  • Finally, the lymph nodes of the neck may enlarge, making it difficult or painful to open the jaw.
  • People with swimmer's ear may experience some temporary hearing loss in the affected ear.

What is chronic swimmer's ear?

Chronic (long-term) swimmer's ear is otitis externa that persists for longer than four weeks or that occurs more than four times a year. This condition can be caused by a bacterial infection, a skin condition (eczema or seborrhea), fungal infection (Aspergillosis), chronic irritation (such as from the use of hearing aids, insertion of cotton swabs, etc), allergy, chronic drainage from middle ear disease, tumors (rare), or it may simply follow from a nervous habit of frequently scratching the ear. In some people, more than one factor may be involved. For example, a person with eczema may subsequently develop black ear drainage. This would suggest of an accompanying fungal infection.

The standard treatments and preventative measures, as noted below, are often all that is needed to treat even a case of chronic otitis externa. However, in people with diabetes or those with suppressed immune systems, chronic swimmer's ear can become a serious disease (malignant external otitis). Malignant external otitis is a misnomer because it is not a tumor or a cancer, but rather an aggressive bacterial (typically Pseudomonas) infection of the base of the skull.
