Trigeminal neuralgia immediate pain relief methods are as follows: 1, drug treatment: the preferred treatment method, mainly carbamazepine, oxcarbazepine, pregabalin capsules, etc.; 2, nerve block treatment: if the patient’s oral drug effect is not good, can increase the trigeminal ganglion or trigeminal nerve trunk nerve block measures, that is, around its injection of local anesthetic, anhydrous alcohol, glycerin, etc., but anhydrous alcohol and glycerin side effects are larger, and the duration of the trigeminal nerve sensory nerve fibers to achieve the purpose of pain relief. However, the side effects of anhydrous alcohol and glycerin are large, and the duration of local anesthetics is short, usually lasting from half an hour to several hours; 3. Minimally invasive interventions: such as radiofrequency thermocoagulation of the trigeminal nerve, that is, by destroying the sensory nerve fibers of the trigeminal nerve to achieve pain relief. There are also percutaneous puncture micro-balloon compression, microvascular decompression, gamma knife radiation therapy, etc. The duration of pain relief is longer and the possibility of pain recurrence is lower.
