Herpes zoster is mainly a cutaneous manifestation with neuralgia, and is usually seen in dermatology. Some patients who have pain first and then no rash go to thoracic surgery, neurology, or pain medicine, especially pain medicine or neurology can also be treated. In terms of antiviral and analgesic treatment, dermatology is more specialized, and all aspects of treatment effectiveness in this area can be taken into account. Therefore, it is advisable to visit dermatology, and dermatology will treat patients according to their conditions. In most clinical patients with tumors, the incidence of shingles and intercostal neuralgia is higher, and the cases of tumor patients after the use of chemotherapy drugs or targeted drugs are also higher. Theoretically, herpes zoster occurs once a year. With the increase in life expectancy of the current population and the increase in co-morbidities, the incidence of this is increasing. If its incidence is high, the frequency and extent of herpes zoster can be reduced by vaccination.
