Herpes zoster is an infection caused by the varicella-zoster virus, which is more common in the middle-aged and elderly population. The incidence is higher when the body’s immune status is lowered, when it stays up late, and when it is combined with other medical problems, such as diabetes, kidney disease, and tumor radiation and chemotherapy. At the same time, oral antiviral treatment with valacyclovir hydrochloride can be given, but only if normal liver and kidney function is determined. In addition, herpes zoster is usually combined with nerve pain, you can consider taking oral methylcobalamin to nourish the nerves, or you can go to the Chinese medicine department for acupuncture and cupping treatment.
