Does herpes zoster have a fever?

Herpes zoster is mainly caused by varicella zoster virus infection. The virus first appears as chickenpox or latent infection, and then appears as herpes zoster again. The human body is attacked by the virus, and the immune system is activated to fight against the virus. When the antigen and antibody bind, fever occurs. Therefore, the early symptoms of herpes zoster may include general discomfort and fever. If fever is below 38.5 ° C, it can be treated by physical cooling, and above 38.5 ° C, medical intervention is required. Patients with herpes zoster show fever relatively rarely, most of them presenting as skin clusters of blisters with obvious nerve tingling.
