What is swimmer's ear (otitis externa)?
Swimmer's ear (also called otitis externa) is a type of ear infection. The infection occurs in the ear canal. Because the ear canal is dark, warm, and can hold water, it makes a perfect environment for water-loving bacteria and fungus to grow.

Otitis externa was given the nickname swimmer's ear because it most commonly affects individuals who spend a lot of time in water, such as swimmers.
