Herpes zoster is a viral disease caused by the varicella-zoster virus and is characterized by neuralgia and clusters of blisters on the skin. The lesions are often distributed unilaterally in bands, mostly not exceeding the midline of the body surface. This disease occurs mostly in the elderly, chronically ill and immunocompromised people, and some young people may also develop the disease because of recent overwork and poor rest. The treatment is mainly based on the principles of antiviral, pain relief and nerve nutrition. However, the specific amount of medication should be based on the condition, and each person has a different location and severity, so the treatment plan should be guided by a clinician after an interview. The conclusion is that herpes zoster can occur anywhere on the body, so it can also grow on the legs.
