Swimmer's Ear is an infection of the outer ear canal, often caused by water that remains in the ear after swimming or bathing. This trapped moisture creates a breeding ground for bacteria, leading to inflammation and discomfort. Symptoms may include itching, redness, and pain in the ear, as well as drainage of fluid. Treatment typically involves keeping the ear dry and using antibiotic ear drops to eliminate the infection. In some cases, over-the-counter pain relievers can help manage discomfort. Preventive measures include using earplugs while swimming and thoroughly drying the ears after exposure to water.
