Neuralgia is known as the “world’s first pain”, and postherpetic neuralgia, because of its stubborn pain and diverse nature, often manifests as needle-like, knife-like and pressure-like pain, which seriously affects the quality of life, social function and sleep quality of patients. The side effects of drugs are also a problem that cannot be ignored. As the earliest and largest tertiary hospital in Shenzhen, the pain department of Shenzhen People’s Hospital has formed pain treatment mainly for spinal pain, neuralgia, soft tissue pain, joint pain and advanced cancer pain after years of development, and has formed the characteristic of minimally invasive pain treatment with “puncture-type target minimally invasive, eliminating the pain of incision”. Our philosophy of pain treatment is to “remove pain and protect nerves”. For post-herpetic neuralgia, the pain department of Shenzhen People’s Hospital, on the basis of various pain management therapies at home and abroad, has creatively applied “CT-guided selective nerve modulation technology” under the support of the pain management concept of “removing pain and protecting nerves”. “The treatment of postherpetic neuralgia has been approved and recognized by all walks of life, benefiting patients with postherpetic neuralgia, and the technique has been summarized in the Chinese Journal of Pain Medicine, the top journal of pain treatment in China. After systematic treatment with this technology, the pain can be significantly reduced, there is no longer any obstacle to sleep at night, and you can basically say goodbye to analgesic drugs after discharge from the hospital. In addition, this technology has high accuracy, good safety, fast onset of action, and no side effects and adverse reactions through CT-guided positioning.
