Patients who have trigeminal neuralgia must go to the hospital and prevent and treat it through appropriate methods. The matters that need attention are as follows: 1. Pay attention to maintaining a good mood; 2. Eat less stimulating food, such as too spicy, too salty or too acidic food; 3. Try to keep the painful facial area from being cold or irritated; 4. Pay attention to distinguishing trigeminal neuralgia from toothache, which is an electric shock-like Trigeminal neuralgia is an electric shock-like and paroxysmal pain, while toothache is a continuous pain; if the pain in the teeth or upper jaw is intermittent, it should be considered trigeminal neuralgia rather than toothache. The headache caused by trigeminal neuralgia is the pain at the top of the frontal area caused by the first branch of the trigeminal nerve, and the pain in the temporal area and auriculotemporal area caused by a small number of them, all of which are lightning-like, electric shock-like and knife-like pain. The treatment of this disease is as follows: 1. Early detection can be treated with oral carbamazepine, oxcarbazepine or gabapentin-like drugs; 2. In cases of poor drug control or complete intolerance, trigeminal nerve destruction and cerebrovascular decompression therapy can be performed, generally try to perform radiofrequency destruction in the terminal branch to reduce the patient’s nerve damage or numbness site, which is conducive to the recovery of the disease.
