An earache typically refers to pain or discomfort experienced within the ear canal or the external ear. Common causes of earaches include ear infections, which can be either bacterial or viral and often result in inflammation and fluid buildup in the middle ear. Another frequent cause is the buildup of earwax, which can cause blockages and pressure on the eardrum. Additionally, injuries to the ear, such as from inserting objects into the ear canal or sudden changes in air pressure, like during air travel, can lead to ear pain. Sinus infections and dental problems can also cause earaches because of pain that moves from one area to another. Treatment depends on the underlying cause but often involves pain relief and addressing the root issue, such as with antibiotics for infections or ear drops for wax buildup.
