it does NOT sound like trigeminal neuralgia as the other post suggested. it does sound like something is irritating your laryngeal nerve w branches into auricular nerve (that would cause ear 'canal' pain, if that is what you are calling 'deep'). and that could be caused by any thyroid inflammation. i would ask ur PCP to send you for an ultrasound. but its been 11mths since you posted, so what did you find out?View Thread
