Herpes zoster is due to the body infected with herpes zoster virus, herpes zoster virus will travel along the nerve line, so the clinical symptoms are often accompanied by pain. The location is consistent with the distribution of the lesions, which are arranged in bands along one of the peripheral nerves, mostly occurring on one side of the body, usually not exceeding the median line.
