Swimmer’s Ear is an infection of the outer ear canal that commonly develops after water becomes trapped in the ear, creating a moist environment where bacteria or fungi can grow. It often causes itching, redness, pain, swelling, and discomfort that may worsen when the outer ear is touched. People who swim frequently, especially in lakes or pools, are at higher risk, but it can also occur after showering or excessive ear cleaning. To help prevent swimmer’s ear, keep ears as dry as possible, avoid inserting cotton swabs into the ear canal, and use well-maintained swimming facilities whenever possible.
