Swimmer's ear (otitis externa) is an infection of the outer ear canal, commonly caused by water exposure, bacteria, or fungi. It leads to itching, redness, pain, and sometimes fluid discharge. If left untreated, the infection can spread. Prevention includes keeping ears dry, using earplugs while swimming, and avoiding inserting objects into the ear. Treatment options typically involve antibiotic ear drops or oral medications for severe cases. Early intervention can help prevent complications and ensure proper healing.
