Shingles (herpes zoster) is an infection caused by the varicella-zoster virus, which is the virus that causes chickenpox. 

Shingles occurs in people who have had chickenpox and represents a reactivation of the dormant varicella-zoster virus. 

The disease generally affects the elderly, although it occasionally occurs in younger and/or immunodeficient individuals. Its accompanying neuralgia is always unbearable.

Local management in traditional treatment focuses on preventing secondary infection while neglect eliminating pain-inducing factors and cutting off the incoming pathway of pain feeling.

As a result, the analgesic effect in traditional treatment was always unsatisfactory.
