1. What are the manifestations of trigeminal neuralgia? Trigeminal neuralgia is a neurological disorder characterized by periodic episodes of severe, paroxysmal pain in the distribution area of the facial trigeminal nerve. It is characterized by sudden onset and stoppage, lightning-like, knife-like, burning-like, intractable and severe pain, lasting for several seconds to several minutes, often accompanied by facial muscle convulsions, lacrimation, salivation, facial flushing, conjunctival congestion and other symptoms, with the aggravation of the disease, the attacks become more frequent, seriously affecting the quality of life of patients. 2. What are the common treatments for trigeminal neuralgia? Currently, there are many clinical treatments for trigeminal neuralgia, and western medical treatment is mainly divided into two categories: invasive and non-invasive. Invasive treatment includes surgery, nerve block therapy, radiofrequency thermal coagulation therapy and gamma knife treatment, which are more expensive and often leave sequelae and side effects. Patients are more likely to accept non-invasive treatments, including Western medicine, Chinese herbal medicine, acupuncture, and physical therapy. Acupuncture has better efficacy in the treatment of trigeminal neuralgia, and has no toxic side effects. 3.What are the characteristics and advantages of infrared thermography acupuncture point selection treatment method? Medical infrared thermal imaging technology is a more advanced detection means, with the advantages of simplicity, intuition, wide range of imaging, and no harm to the human body. By applying infrared thermographic display technology, through scanning the facial thermogram of trigeminal neuralgia patients and analyzing the patient’s facial thermogram, the patient’s abnormal acupuncture points are diagnosed and provided to the acupuncturist for treatment, which has changed the disadvantages of traditional treatment in which the patient’s description is not accurate and the doctor takes acupuncture points based on experience. The infrared thermogram of the face of trigeminal neuralgia patients taken by the infrared thermography camera can objectively reflect the state of blood circulation of local tissues, the metabolic status of local tissues and the functional state of nerves. Based on the above examination results, targeted acupuncture can quickly unblock meridians, improve facial microcirculation, inhibit pain transmission in nerve fibers, and achieve better therapeutic effects. The combination of acupuncture therapy and infrared thermal imaging technology will make acupuncture selection more objective and targeted.
