Glossopharyngeal neuralgia is believed to be caused by irritation of the glossopharyngeal nerve. In many cases, the source of the irritation is not found. Possible causes that have been proposed include various things pressing on the glossopharyngeal nerve such as an abnormally positioned artery, growths at the base of the skull, or tumors or infections of the throat and mouth. Rarely, the condition may be attributable to a tumor in the brain or neck, an abscess, an aneurysm in an artery in the neck, or multiple sclerosis.
