Herpes zoster is caused by a virus that enters the nerves. Postherpetic neuralgia is defined as postherpetic pain that persists for more than one month after clinical cure. Postherpetic neuralgia is one of the persistent pain disorders that plague middle-aged and elderly patients. The duration of pain can be as short as 1-2 years or as long as 10 years, with a general history of 3-5 years. The clinical manifestation is characterized by hypersensitivity to pain, which can produce severe and unbearable pain with a light touch. The patient’s pain is often spontaneous lightning-like or tearing-like pain, which often makes the patient restless during the attack, and most patients are often accompanied by a more pronounced persistent burning pain. The occurrence of post-herpetic neuralgia is related to the pre-diagnosis of herpes zoster and the lack of timely and correct treatment. Most patients are initially misdiagnosed as having radiating pain from heart disease and painful gallbladder attacks and treated, during which the virus multiplies in the body, aggravating the damage to the nerves by the virus and creating incurable pain. Postherpetic neuralgia is one of the intractable pains that are difficult to be cured by modern medicine. There is no special treatment for pain in Western medicine, but through years of clinical observation, we found that acupuncture is effective for this postherpetic neuralgia, and dozens of such patients were treated clinically with definite results, so we suggest that such patients try acupuncture treatment.
