The treatment plan is mainly based on antiviral treatment, and acyclovir cream is a topical antiviral drug, which is usually cured in about 1 week of treatment. Herpes zoster is caused by varicella-zoster virus infection, mainly manifesting as erythema and blisters in a band-like distribution, with paroxysmal pinprick-like pain.
