Cerebral neuralgia is the occurrence of pain in the nerves of the head and face, and the common causes are: 1. trigeminal neuralgia: trigeminal neuralgia occurs in the face, and the common causes of trigeminal neuralgia are vascular compression, arteriosclerosis leading to distortion of the blood vessels, which compresses the trigeminal nerve; other tumors, inflammation, degenerative diseases, which can cause trigeminal neuralgia; 2. occipital neuralgia: occipital neuralgia is mainly in the occipital region, and the most common cause is cervical spondylosis. Cervical spondylosis can compress the occipital nerve because of bone spurs and herniated discs, and inflammation, tumors, diabetes or lead poisoning can cause occipital neuralgia; 3, linguopharyngeal neuralgia: linguopharyngeal neuralgia is mainly in the throat, and the main causes of linguopharyngeal neuralgia are various inflammatory diseases, tumors, diabetes and vascular compression.
