The following we come to understand: 1, do not care about hygiene of the crowd: many patients are due to inattention to personal hygiene, resulting in a viral infection. Such as herpes zoster is prone to involve the first branch of the trigeminal nerve causing pain. Demyelination, trigeminal neuralgia is caused by demyelination of the trigeminal nerve sensory roots or semilunar ganglion or peri-trigeminal branches by compression or damage. 2, people with irregular life: many people due to the regular irregular life, black and white, long time to hang out in nightclubs and other also life places, resulting in a decline in body resistance. Climate change is also a predisposing factor for trigeminal neuralgia, or being blown by the wind, or hot and cold at first, can make the pain intensify, so we should pay attention to weather changes when we go out, pay attention to keep warm. 3, people who do not pay attention to diet: excessive vegetarian or do not eat staple foods, it is likely to also aggravate trigeminal neuralgia.
