Herpes zoster is a skin disease caused by varicella-zoster virus infection, known to the people as “tangled dragon” and “tangled snake”. The disease occurs in the spring, autumn and winter, the recent change of seasons, but also the high incidence of the disease triggers. The elderly are more susceptible to this disease because of their poor health and weak resistance. The virus enters the bloodstream through the respiratory mucosa to form viremia, and chickenpox or occult infection occurs. After the virus is latent in the posterior root ganglion of the spinal cord or the sensory ganglion of the brain nerve, when the body’s resistance decreases (trauma, fatigue, tumor or post-illness weakness, etc.), the latent virus is activated to replicate along the nerve to the innervated skin, resulting in blisters, inflammation and necrosis of the affected nerve, and neuralgia. The site of occurrence can be in the forehead, back, waist, abdomen, but also in the extremities, head and face, and around the anus. The clinical features of herpes zoster are clusters of erythema, papules, blisters, and obvious neuralgia along the unilateral peripheral nerves, but in clinical practice, we often encounter cases where the rash appears very late or where the rash is painful but not present (stroke-type), making the diagnosis more difficult for the doctor and more painful for the patient. Herpes zoster on the head and face is sometimes treated as toothache or migraine; herpes zoster without a rash on the chest is misdiagnosed as pleurisy or angina; herpes zoster on the abdomen is sometimes treated as cholecystitis, gallstones, or appendicitis and sent to the operating room; herpes zoster on the lower back has also been reported as a kidney ureteral stone. Therefore, when there is unexplained pain in a certain area, especially if it is unilateral and consistent with the innervation, and the treatment is not effective as other diseases, you should be alerted to herpes zoster and go to a dermatologist in time to avoid delaying the disease. Also, improper or untimely treatment can cause postherpetic neuralgia. Postherpetic neuralgia is a condition in which herpes zoster is not treated effectively and the pain persists even after the herpes has subsided, and can last for months or even years. The incidence of postherpetic neuralgia accounts for as much as 10-34% of patients with shingles, and the older the patient, the higher the incidence, with the incidence of postherpetic neuralgia accounting for more than half of patients over the age of 60. Patients suffer from chronic unbearable pain that makes them restless during the day and unable to sleep at night. Since this pain is very difficult to treat, many patients are so miserable that they are almost desperate, and some of them choose to commit suicide to end their pain, which is regrettable! There are also some elderly patients who die because their chronic pain has aggravated their original disease, which is a very sad thing that we do not want to see. Therefore, in our clinical work, we use western medicine anti-viral nerve nutrition, the use of Chinese medicine for diagnosis and treatment, the use of Chinese herbal medicine, acupuncture and bloodletting to stimulate peripheral nerve recovery and other methods of combining Chinese and Western medicine to treat herpes zoster and postherpetic neuralgia, for the majority of patients to relieve the disease. In conclusion, preventive treatment is the most ideal treatment, which means that we should pay attention to the effective and thorough treatment of herpes zoster in the acute phase, especially for elderly people with herpes zoster, so that the lesions are controlled to a minimum.
