As a rehabilitation doctor practicing for more than 30 years, I have always taken it as my mission to relieve the pain of my patients. Seeing countless patients with herpes zoster neuralgia, who have suffered from pain for a long time, I have made this disease my main focus. With the accumulation of clinical practice, I also continued to deepen my understanding of this disease. Herpes zoster is an ancient virus that lurks in our bodies and causes a viral nerve-damaging disease. Although this virus has been around since ancient times and has been with humans for millions of years. But our knowledge of it is still rather superficial. Here is what we know about this virus, this disease: I. Where did such an old virus come from? The most important characteristic of this virus is that it infects only us humans. It is often the elders at home who develop shingles that transmit the virus to children, who may develop chicken pox after contracting the virus and recover in 2-3 weeks, but the virus lurks down and then develops shingles again after the body’s immune function declines in adulthood, once again passing the virus to the next generation, and this is how the virus spreads from generation to generation in our human race. This is why more than 90% of our body has the presence of this virus. Herpes zoster is not only a skin disease, but also a neurological disease. It is a virus that is activated from our sensory ganglia, synthesizes new viruses, and then comes out along the nerve fibers and sprays from the sensory nerve endings to the skin before finally reaching the skin. So that our nerve damage in the front, and it is difficult to repair, our skin damage in the back, and the skin healing ability is strong, leaving a legacy of biting pain, is a manifestation of nerve damage, often making the patient painful, so it is more a nerve damage disease. The post-herpetic neuralgia is a persistent disease and a worldwide problem. Post-herpetic neuralgia has complex clinical pain types, accompanying clinical symptoms and various subtypes. Postherpetic neuralgia is mainly the result of the virus invading and damaging the sensory nervous system, the pain is the manifestation, the patient’s feeling, behind the pain is the virus eating the nerve destruction. Fourth, but the current treatment is mostly in antiviral and analgesic. Unfortunately, postherpetic neuralgia is not sensitive to general analgesic methods. In many cases it is not yet possible to achieve good therapeutic results. Therefore, analgesia alone is not enough to promote the repair of injured nerves as early as possible in order to cure the pain completely. After years of research and development, we have proposed a sequential treatment program: improving immunity, anti-viral and nerve protection go hand in hand in the early stage; nourishing nerves and promoting nerve repair and analgesia in the later stage. We have accumulated experience in treating 10,000 patients at different stages, and our efficiency (pain reduction by 2 points) reaches 85%; significant efficiency (pain less than 3 points, stop taking analgesics) reaches 80%. It proves that our treatment strategy of nourishing nerves and promoting nerve repair is the root of pain treatment.
