Trigeminal neuralgia is one of the common clinical facial pains, mainly manifested as sudden onset of paroxysmal “electric shock-like”, “cutting-like”, “tearing-like” pain in the distribution area of the trigeminal nerve. The onset often lasts for a few seconds or 1 to 2 minutes, with sudden onset and stop, and the interval is completely normal. For decades, many clinical workers have used many methods to treat trigeminal neuralgia: from medication, injection therapy, radiofrequency therapy, adriamycin injection therapy, gamma knife, to open surgery such as microvascular decompression, etc. While many patients have been cured, one thing is undeniable, that is, “trigeminal neuralgia recurrence”. Here I will talk about the possible causes of recurrent trigeminal neuralgia. Factors leading to recurrence of trigeminal neuralgia] 1. abnormal excitatory discharge of the nucleus of the trigeminal nerve bundle and sensory nucleus of the brainstem; 2. damage to the thalamus, which is one of the causes of recurrence of trigeminal neuralgia; 3. demyelination of the sensory root of the trigeminal nerve or the semilunar ganglion or the peripheral branches of the trigeminal nerve by compression or damage, such as anatomical abnormalities, vascular malformations, inflammation of the periosteum of the bone foramen, arteriosclerosis, etc.; 4. the maxilla and mandible Pathological bone cavity, although the etiology is multifaceted, ultimately leads to abnormal cranial brain cell discharge, the appearance of trigeminal brain stem cell evoked potentials, and painful episodes. Trigeminal neuralgia is often recurrent and difficult to cure because the evoked potentials are generated by slight stimulation and can even be spontaneous; 5. “The trigeminal nerve is a sensory nerve. The trigeminal nerve is a sensory nerve, and its characteristic is that it is prone to regeneration. Some basic studies have confirmed that after the nerve is avulsed, regeneration can occur in three to six months, regenerating along the original direction of travel; 6. This is the most common factor that induces the recurrence of trigeminal neuralgia, that is, bad habits or inattention to life (cold stimulation, touch stimulation, food stimulation) or mood swings. Lifestyle precautions] 1. Resolutely quit bad habits, such as smoking and drinking. Studies have shown that the habit of smoking or drinking can induce an early relapse of trigeminal neuralgia. 2, seasonal changes, especially in summer, should pay attention to the regularity of living and not to be blown by cool breeze all the time, especially the direct wind from fans or air conditioners. 3, adjust the mind, keep a calm state of mind, avoid anxiety, anger, fire and fret and distress so that you can not sleep, in the state of anxiety, irritability. 4, moderate physical exercise in the morning and evening, at least 10,000 steps of slow walking every day, you can play table tennis, rope skipping or participate in square dance activities. 5.In daily life, such as shaving, washing face, brushing teeth, etc., try to avoid stimulating the trigger point. 6.Some patients are patients whose pain is induced by swallowing or chewing, they usually need to eat a liquid diet, and firmly eliminate eating fried things, irritating food, seafood products and hot food, etc. 7, the diet should be scientific, trigeminal neuralgia patients should usually eat more fruits containing oranges, oranges and other vitamin-rich fruits. Eat more vegetables and supplement various trace elements to ensure the normal metabolism of nerves. In conclusion, most diseases are treated with the possibility of recurrence. Neurological diseases, especially trigeminal neuralgia, are more likely to relapse. No matter which treatment method is used, the recurrence rate of trigeminal neuralgia is above 20%. However, according to the author’s clinical experience, it is believed that the patient’s habits and preferences can affect the recurrence of trigeminal neuralgia. Generally speaking, patients with trigeminal neuralgia should have a regular life and personal hygiene. In terms of mental state, they should not get angry often, and should not get emotional. Daily habits should prohibit washing the face with cold water, especially in the cold autumn and winter seasons. In addition, trigeminal neuralgia patients should participate in some physical exercises suitable for their physical fitness to enhance the body’s resistance to disease.
