Most ear pain is caused by diseases of the ear itself, and in a few cases, the ear pain is due to other causes of ear involvement pain. If there is paroxysmal pain in the ear, consider it to be caused by otalgia. With otalgia, there can be ear canal throbbing caused by auriculotemporal neuralgia of the trigeminal nerve, and throbbing pain caused by glossopharyngeal neuralgia. If there are diseases of the teeth, throat, jaw joints, and the neck, respiratory and digestive tracts, they can cause reflex pain in the ear through the trigeminal nerve, vagus nerve, lingual nerve, lesser occipital nerve, and the greater auricular and facial nerves. If the earache is caused by inflammation, it is often a persistent pain in the ear. If the ear pain is caused by temporomandibular joint dysfunction, it often manifests as a dull pain in the ear canal and pressure pain at the temporomandibular joint. The specific cause of the ear pain needs to be examined at an otorhinolaryngology department before a preliminary diagnosis can be made.
