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.
If you've had TMJ before, even if you have different symptoms with it now, it could still be from TMJ. I do think that TMJ can indeed cause sharp ear pains (I've heard). If you don't get better in 8 days, be sure to let your ENT know and see what he suggests as a next step.
