Li Danyang, 74 years old, had severe pain in her left anterior chest with no obvious cause, rushed to the hospital and underwent several tests, including electrocardiogram, cardiac ultrasound and chest CT, but no abnormalities were found. The pain was not relieved. She visited the dermatology and neurology departments successively, but the pain was still there, although the herpes was reduced. Therefore, he came to the pain department for consultation. After taking a detailed history, the chief of the pain department diagnosed herpes zoster. The patient was given a thoracic nerve block, anti-neuralgia medication and nerve nutrition medication, as well as antiviral medication to solve the main problem – pain. Diana Li was very satisfied with the treatment result. The director explained to Li that herpes zoster is an acute inflammatory skin disease caused by varicella-zoster virus, known in Chinese medicine as “tangle waist fire dragon”, mainly characterized by clusters of skin blisters, along one side of the nerve to do a cluster of band distribution, accompanied by obvious neuralgia, herpes zoster patients can obtain lifelong immunity to the virus, the age of prevalence of the elderly Herpes zoster has a lifelong immunity to the virus and is most prevalent in the elderly, with the thoracic nerve and trigeminal nerve innervated skin areas. The treatment of this disease is based on antiviral, analgesic and nerve nutrition. The pain department specializes in interventional subnerve modulation methods to treat this type of disease, which can better prevent the occurrence of posterior neuralgia. Experts suggest that shingles needs to be treated early, and if left with post-herpetic neuralgia it will be an intractable and stubborn disease, a world-class problem for treatment, so patients are advised to seek treatment early. The incidence of shingles increases with age, and young people are also susceptible to the disease when their immune system is low. Another special case to be noted is that the area involved in herpes may also be triggered by tumors, osteophytes, local inflammation and other factors in the nerve in that area, and if the disease is found, a systematic examination should be performed to exclude other disease triggers.
