Shingles is purely a self-limiting disease as far as viral diseases are concerned, and it will get better without treatment. However, once herpes zoster, blisters out on the skin surface and produces severe pain, in case of untimely and inappropriate treatment, it may produce the following sequelae: 1. the most uncomfortable is pain, pain that causes great suffering to the patient, pain that is intense, such as the patient often said knife cut-like, needle gouge-like, fire-like. In short, the first sequel is severe pain, pain is unbearable; 2, relatively simple is an infection on the surface of the skin, if the infection is serious, after treatment, there is a possibility of scarring, skin infection is not very strong, only limited to the surface, will not leave scars. Do not be afraid and nervous, if the body’s resistance is very low, in addition to the skin mucous membrane infection, may also spread to other parts of the infection; 3, is relatively rare, but a more terrible sequelae, it will spread along the nerve roots to the nerve center. The virus originally spreads along the nerve roots to the periphery of the nerve and to the surface, but in the case of extreme decrease of the body’s resistance, it may spread along the nerve roots to the nerve center, causing viral infection of the nerve center. Once a viral infection of the nerve center occurs, it can lead to viral encephalitis, which has very serious consequences.
