Trigeminal neuralgia mostly occurs in the middle-aged and elderly, slightly more women than men, the pain site in the face, the pain attack as if lightning-like, knife like, burning like, there are trigger points, may be triggered by washing the face, brushing teeth, talking, eating touch, stubborn attacks on the physical and mental health of patients, life and work and quality of life caused serious impact, so that patients can not live in pain, seriously affecting the survival of patients. The patient’s survival is seriously affected. Ms. Wang had toothache for more than two years, and the pain increased whenever she chewed or ate. At first, she did not pay much attention to it and did not undergo treatment. Later, she thought it was a dental disease and went through many hospitals, but after medication and acupuncture treatment, it did not have any effect, and the pain not only did not reduce, but became heavier and heavier. After examination, she learned that it was trigeminal neuralgia that was causing the damage to the maxillary branch nerve, and finally the neurosurgeon treated her with microvascular decompression surgery, which was effective and reduced the pain. ”Clinically, trigeminal neuralgia is often misdiagnosed as toothache, and many patients will go to the dentist, but after extracting a few teeth, they don’t see any improvement and still feel the pain.” Doctors say that, in fact, some toothache without a cause may be trigeminal neuralgia at work. According to the doctor, trigeminal neuralgia is one of the most common neuropathic pain, which is triggered by facial nerve damage. It is mainly manifested as recurrent episodes of severe pain in the distribution area of the trigeminal nerve on one side of the face. The onset is sudden and abrupt, and patients often feel instantaneous lightning-like, knife-like, or burning pain. Although the disease is not life-threatening, it seriously affects normal life. So how to treat trigeminal neuralgia? In this regard, Professor Wang Xuelian said that manifest microvascular decompression can achieve a one-time cure, and even if there is a delayed cure, there is often no need to continue taking oral medication to relieve symptoms. The symptoms of spasm disappear immediately after surgery in most patients. Only a few patients, with more severe nerve damage, require a period of nerve function recovery during which symptoms gradually resolve. Doctors remind that with the arrival of winter, trigeminal neuralgia enters a high incidence period. Cold weather can cause frequent attacks of trigeminal neuralgia, and middle-aged and elderly people must be alert, pay attention to the warmth of the head and face in general, and go to regular hospitals as soon as possible after symptoms appear. In the diet should be reasonable and regular, avoid stimulating spicy food.
