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.
Swimmer's ear may be acute or chronic.
Swimmer's ear is more common among teenagers and young adults. Rarely it is seen along with middle ear infection (otitis media) or upper respiratory infections such as colds.
Swimming in polluted water can lead to swimmer's ear. Water-loving bacteria such as Pseudomonas, as well as other bacteria or fungi (in rare cases), can cause ear infections.
Other causes of swimmer's ear include:
Trying to clean wax from the ear canal with cotton swabs or small objects can irritate or damage the skin.
Long-term (chronic) swimmer's ear may be due to:
The doctor or nurse will examine you and look inside your ears. The ear area will look 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 to see because of a swelling in the outer ear. Or, the eardrum may have a hole in it. This is called a perforation.
A sample of fluid may be removed from the ear and sent to a lab to identify any bacteria or fungus.
Ear drops containing antibiotics are usually given, usually for 10 to 14 days. 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. Your doctor or nurse can show you how to do this.
Other treatments may include:
People with chronic swimmer's ear may need long-term or repeated treatments to avoid complications.
Placing something warm against the ears may reduce pain.
When treated properly, swimmer's ear usually gets better.
The infection may spread to other areas around the ear, including the skull bone. In elderly people or those who have diabetes, a severe infection called malignant otitis externa is a possibility. Malignant otitis externa is treated with high-dose antibiotics given through a vein.
Call for an appointment with your health care provider if:
