âº A donor is also someone who gives blood or who agrees to give an organ or body part to help someone else. (Definition of âdonorâ from the Cambridge Academic Content Dictionary Â© Cambridge University Press)
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.
Perforation of the eardrum by an injury causes sudden severe pain, sometimes followed by bleeding from the ear, hearing loss, and noise in the ear (tinnitus). The hearing loss is more severe if the chain of ossicles has been disrupted or the inner ear has been injured.
