Otitis externa, also known as swimmer’s ear, is an infection or inflammation of the outer ear canal, usually caused by bacteria or fungi. It often develops after water remains trapped in the ear, creating a moist environment for germs to grow.
Treatment involves cleaning the ear canal and prescribing antibiotic or antifungal ear drops. Pain relievers and anti-inflammatory medicines may be given for comfort. In severe cases, ear wick insertion or oral medication may be required.
