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.
Most people assume earaches and ear pain happen only to children, but they can also happen to adults. An earache may affect one or both ears, but the majority of the time it's in one ear. Ear pain may be dull, sharp, or burning, and it may feel constant or come and go. Pain in the ear can have multiple causes.
