Middle ear and outer ear infections are common causes of sharp ear pain. An infection of the inner ear, formally called labyrinthitus, may cause sharp pain as well as a loss of balance. People with a bad cold or the flu often experience sharp ear pain.
This tube drains fluid that is made in the middle ear. If the eustachian tube becomes blocked, fluid can build up. This may lead to pressure behind the eardrum or an ear infection. Ear pain in adults is less likely to be from an ear infection. Pain that you feel in the ear may be coming from another place, such as your teeth, the joint in your jaw (temporomandibular joint), or your throat. This is called referred pain. Causes of ear pain may include: Arthritis of the jaw.
