It is a viral disease, mainly caused by varicella-zoster virus infection. This virus is usually latent in the neurons and will recur when a person’s immunity decreases or when he or she is tired, and generally patients with normal immunity get shingles almost only once in their lives. The treatment of herpes zoster requires antiviral therapy and nerve nutrition therapy, and generally oral acyclovir tablets or vaxilovir tablets, but the utilization of intravenous infusion is better than oral, generally intravenous infusion of acyclovir injection, 0.5g each in the morning and evening, along with oral vitamin B1 and methylcobalamin and other nerve nutrition drugs. If the pain is severe, you can take oral celecoxib, or you can combine it with oral Chinese medicine for regulation.
