The so-called entangled snake is the medical term for shingles. It is mainly caused by the varicella zoster virus. When the body’s resistance decreases, the virus invades the nerves in the epidermis, and it makes the person feel particularly painful and unbearable. Shingles, in itself, does not cause death. Although the treatment is troublesome, but after a period of treatment, as long as there are no sequelae, they will get better. If the sequelae remain, the effect is not too good. The disease itself is not fatal. If herpes zoster occurs and then the patient dies, some other factors and complications, such as viral pleurisy, meningitis, and some other complications due to pain, should be considered to cause death.
