Postherpetic neuralgia is one of the most well-treated conditions in the pain department. The reason is simple: first, the diagnosis is clear; second, the treatment is effective. I have encountered many patients with PHN in the clinic, and most of them belong to two categories: the first, older patients who are persistent. They know exactly what they have, but they did not anticipate that the disease is so stubborn and pestering, and they do not know that a few of them will have a long recovery time from treatment; secondly, new patients who are panicked. The second category, the new patients who are panicked, are hit hard by the sudden and severe pain. They do not know what they have and do not understand why the pain is so intense when the herpes has subsided. Many patients do not receive regular antiviral therapy, analgesia and neurotrophic treatment in the early stages of shingles, and this cannot be ruled out as a cause of their post-herpetic neuralgia. I am attaching a recently written article with data from patients in our hospital in the hope that more people will learn about PHN as a disease, or at least be alert to it, know that they can go to the pain departments of major hospitals, and know that if they are >70 years old with PHN, the treatment may take longer and they may have to face various problems such as the need for long-term medication.
