Herpes zoster is an acute inflammatory skin disease caused by the varicella-zoster virus, commonly known as “snake pox”, “spider sores”, “snake pan sores” and so on. It has been reported that about 10% of patients have residual neuralgia after the onset of herpes zoster, and the incidence of postherpetic neuralgia is highest in elderly patients over 60 years of age, reaching 50%-75%. The main manifestation of postherpetic neuralgia is local paroxysmal or persistent burning, stabbing, throbbing, cutting pain, which can be accompanied by numbness, sensory hypersensitivity, abnormal sensation such as ant walking sensation, which affects rest, sleep, and mental status in serious cases, and some patients dare not even touch their clothes due to severe pain, which is the phenomenon of pain allergy. At present, the pain department applies the international advanced crestal electrical stimulation treatment to provide timely and effective interventions for patients in the subacute stage of herpes zoster, which can treat the intractable pain in the subacute stage and avoid the transformation into the intractable postherpetic neuralgia. The cremasteric electrical stimulation (SCS) is an internationally advanced and effective means of treating intractable pain. A slim electrode is placed in the epidural cavity of the spinal canal and stimulates the conduction bundle and posterior horn sensory neurons of the posterior column of the cremasteric medulla through a weak electric current, which induces the release of its own endogenous analgesic substances, such as enkephalins and endorphins, through electrical stimulation, thus exerting an endogenous analgesic effect and shutting down the pain information The endogenous analgesic effect can shut down the transmission of pain information, thus relieving and blocking the pain sensation. Patients with spontaneous and touch-evoked pain are significantly relieved after SCS treatment, and the vast majority of patients can have their pain relieved after about two weeks of treatment. It is a minimally invasive procedure with minimal trauma (only one needle eye) and little pain. It is called “green therapy” because it does not use any drugs and does not destroy nerves.
