In otitis externa, the outer ear canal becomes inflamed, usually due to a bacterial, viral, or fungal infection. It is sometimes called “swimmer’s ear,” because persistent moisture in the ear increases the risk of infection.
The condition may also occur as part of a general skin disorder, such as eczema.
Symptoms of otitis externa include swelling, discharge of pus from the ear, itchiness or pain in the ear canal, and sometimes temporary hearing loss.
Often the only treatment needed is to keep the ear clean and dry until the infection clears up. If it persists or is severe, medication to treat the infection and relieve symptoms may be prescribed
