Neuralgia from chickenpox, generally referred to as herpes zoster neuralgia caused by the varicella zoster virus, is partially self-limiting, while older people with underlying medical conditions and low immunity do not self-limit. The varicella zoster virus involves the skin as well as the nerves, causing more pronounced pain, and is a self-limiting condition. Some patients are younger, have no underlying disease, and the body’s immune system is easy to recover, and this condition usually does not result in postherpetic neuralgia and can heal on its own. However, with age, especially after the age of more than 60 years old, immunity decline or at the same time the existence of some underlying diseases, the course of this case will continue for a longer period of time, the symptoms of neuralgia is obvious, can not be self-healing, many patients adhere to the treatment, there will still be residual neuralgia, severe neuralgia, which can last for more than a year, or even several decades. It is recommended that patients seek timely medical treatment, early treatment to reduce the incidence of residual neuralgia.
