Glossopharyngeal neuralgia is a paroxysmal and severe pain that occurs in the posterior pharyngeal wall, tonsils, and root of the tongue of the body. It is significantly more common in men than in women and usually develops after the age of 40. Glossopharyngeal neuralgia is usually caused by demyelination of the nerve, aneurysms, tumors, and localized arachnoiditis. Common symptoms in patients with glossopharyngeal neuralgia include dehydration, cardiac arrhythmia, paroxysmal pain, and hypotensive syncope. Pain is the main manifestation of glossopharyngeal neuralgia. Phenytoin sodium, vitamin B1, vitamin B12 and oral carbamazepine are common medications used to treat patients with glossopharyngeal neuralgia. If the patient is in the early stage of the neuralgia, the effect of medication is very good. In the late stage, the effect of medication will gradually diminish, and surgery is usually taken to treat it. Patients with lingual pharyngeal neuralgia should develop good habits in daily life, try not to eat stimulating food, and do regular review of the body, timely detection, and timely treatment.
