Herpes zoster is a clinically common viral skin disease caused by the varicella-zoster virus invading the subcutaneous nerves. Herpes zoster is often distributed unilaterally along the body in a band, manifesting as clusters of blisters on an erythematous base. It is important to give active antiviral and nerve-nourishing treatment. Generally, within 2-3 days of the onset of the disease, the most effective antiviral drugs are given, which can significantly shorten the course of the disease and inhibit the development of the rash. The treatment is mainly oral vaxilovir or famciclovir, mecobalamin nerve therapy, while the patient should pay attention to rest and enhance immunity.
