Swimmer's ear is more common among children in their teens and young adults. It may occur with a middle ear infection or a respiratory infection such as a cold.

Exams and Tests
The health care provider will look inside your ears. The ear canal area will look red and swollen. The skin inside the ear canal may be scaly or shedding.
Touching or moving the outer ear will increase the pain. The eardrum may be hard to see because of a swelling in the outer ear. 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 look for bacteria or fungus.
In most cases, you will need to use ear antibiotic drops for 10 to 14 days. If the ear canal is very swollen, a wick may be put into the ear. The wick will allow the drops to travel to the end of the canal. Your provider can show you how to do this.
Other treatments may include:
People with chronic swimmer's ear may need long-term or repeated treatment. This will to avoid complications.
Placing something warm against the ear may reduce pain.
Swimmer's ear most often gets better with the proper treatment.
The infection may spread to other areas around the ear, including the skull bone. In older people or those who have diabetes, the infection may become severe. This condition is called malignant otitis externa. This condition is treated with high-dose antibiotics given through a vein.
