Trigeminal neuralgia refers to the sudden onset of “cutting, electric shock, or tearing” pain in the distribution area of the trigeminal nerve. It is a common and stubborn disease of the craniofacial region, which not only has a high incidence but also causes a lot of pain to patients. After a lot of clinical and epidemiological research, clinical experts believe that there are five main factors that trigger trigeminal neuralgia on a daily basis, such as lack of nutrition, mental stimulation, pain trigger points, irritating food, and climate change. Lack of nutrition Clinically, many patients suffer from trigeminal neuralgia because they are vegetarian or do not eat staple foods, blindly dieting, and their bodies lack the necessary nutrients to trigger the pain. Excessive vegetarianism or not eating staple foods is likely to aggravate trigeminal neuralgia as well. The nerve is a tissue that burns and consumes sugar, and a lack of vitamins can cause lactic acid to accumulate and invade the brain, poisoning the central nervous system and weakening the ability of brain tissue to consume oxygen, causing temporary spasms. Second, mental stimulation Mental stimulation is an important factor in triggering trigeminal nerve pain. There are various personalities, some of them are “depressive or anxious”. In the face of daily trivialities, it is impossible to “step back and take a step forward”, always “calculating”, “can not see”. Such a personality will lead to mood and mood “dysregulation”, all day frown, the result is to cause liver depression and qi stagnation, depression for a long time into fire, up to disturb the brain, and lead to pain attacks. In the same pain stimulation, emotional calm people than emotional tension to the pain of the feeling to be small, pain response light. Third, the pain “trigger point” clinical research, many patients with trigeminal neuralgia, in the face has one or more particularly sensitive “trigger point”, a little inattention will trigger the pain, and radiation to the whole body. The location and size of the trigger points vary, even down to a point or a whisker, mostly in the lips, nose, cheeks, corners of the mouth, tongue and eyes. Fourth, irritating food too cold, too hot, or irritating food can also become the cause of trigeminal neuralgia, such as the nicotine of cigarettes will cause vasoconstriction, drink strong tea to enhance neural excitability triggered by small artery spasm, dry cheese, pickled fish and pickles contain more tyrosine, ham contains nitrite, these foods can cause cerebral vasodilatation, stimulate the nerve cause pain. In addition, seafood, eggs, milk, chocolate, beer, coffee, oranges and tomatoes can also lead to the dysfunction of cranial vasodilation and contraction. The occurrence of trigeminal neuralgia is closely related to the change of seasons. Many patients “fall sick” in autumn and winter, often when the temperature drops, the stimulation of wet and cold will lead to the occurrence of trigeminal neuralgia. Clinically, we can see that even in summer, some people who blow directly on “electric fans” and “air conditioners” for a long time can cause pain. Therefore, climate change is also a predisposing factor for trigeminal neuralgia, and the pain can be aggravated by the wind or the heat and cold at first. The five triggering factors of trigeminal neuralgia are more common in our daily life, we must actively avoid these factors and do a good job of preventive measures, only then can we avoid being attacked by the disease.
