Herpes zoster, or medically known as herpes zoster, has the form of a red band on which blisters, even pustules and blood blisters, appear, and is folk called serpentine sores. The pathogen is a virus called varicella-zoster virus, which often attacks people with poor resistance. The virus is more active during the change of seasons, and overwork, poor rest, poor sleep, and excessive stress are all causes of poor immunity, which can easily lead to snakebite infection. If you get snakebite, it is recommended that you go to a hospital as soon as possible and see a regular doctor for diagnosis and treatment. If delayed there may be posterior neuralgia, some people may be in pain for six months or even a year, and the consequences do not pay off.
