The blisters of shingles cannot be lanced on their own. Blisters of shingles cannot be punctured because of the risk of infection and transmission when they are punctured on their own. First, there is no guarantee that the tools used to puncture the blisters are sterile, and contact with the lesions may lead to invasion of germs; second, after the blisters are punctured, the local tissues lose the isolation of the outermost layer of the skin, and come into direct contact with external pathogenic germs, which may also increase the risk of infection. In addition, there is a large amount of virus in the fluid in the blisters, and there is a risk of spreading the virus if you come into contact with others after puncturing. If herpes zoster is diagnosed, it is recommended that standardized treatment be carried out as early as possible to minimize the adverse effects of the disease, and not to deal with it blindly on one’s own.
