H60: Otitis externa

Otitis externa, commonly known as swimmer's ear, is a group of conditions that primarily affect the outer ear and ear canal. These conditions occur when the protective skin in that area gets damaged, allowing bacteria or fungi to penetrate and cause an infection. Certain activities such as swimming or the use of ear plugs can increase the risk by creating moist, warm conditions in the ear, which are ideal for bacterial growth. Some common symptoms include pain, a feeling of fullness in the ear, hearing loss, and discharge. Over time, if left untreated, otitis externa can lead to more serious infections spreading to other parts around the ear. Although it is typically a short-term condition, in some individuals, it can become chronic, persisting for more than three months. This is often due to underlying conditions like allergies or skin disorders.
