Eagle syndrome (also termed stylohyoid syndrome, styloid syndrome, styloid-stylohyoid syndrome, or styloid–carotid artery syndrome) is a rare condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck. Since the brain to body's nerve connections pass through the neck, many seemingly random symptoms can be triggered by impingement or entanglement. [Source: Wikipedia
