Shingles is a common condition, with more than 50% of adults having an episode sooner or later in their lives. Many people suffering from shingles experience unbearable pain, a heartbreaking pain that cuts through the heart, keeps people up at night, is unforgettable, and even painful. Herpes zoster is a nerve-damaging disease. The main reason why herpes zoster produces this excruciating nerve pain is because the varicella-zoster virus invades and damages the corresponding sensory nerves. Therefore, herpes zoster is not only a skin disease, but also a nerve-damaging disease. The current conventional antiviral treatment often takes 2 to 3 weeks. The onset of herpes zoster also takes 2 to 3 weeks from the start of local skin pain to the fading of the herpes. In fact, this is a complete process of the virus raging and attacking the nerves, so some patients experience severe pain at an early stage, which makes people feel like they are worse off than dead. This means that our current treatments may not be really effective in controlling the progression of the disease, and more seriously, they are not effective in blocking the virus from attacking the nerves and controlling the pain in a timely and effective manner. It is generally considered that after the rash of herpes zoster has subsided, local pain that persists for more than 3 months is called postherpetic neuralgia. The typical symptoms are: severe pain in the skin at the site of the original herpes. Some people have localized paroxysmal or continuous burning, stabbing, throbbing, cutting pain, some people cannot touch, and even rubbing clothes can cause “burning” kind of burning pain, the pain area is mixed with numbness or unbearable scratching, that strange itchy taste, accompanied by a variety of pain, seriously affect rest, sleep, mental state, etc. The pain is accompanied by a variety of pain, which seriously affects rest, sleep, mental state, etc. Under current medical conditions, more than 30% of patients over 50 years of age with herpes zoster have post-herpetic neuralgia, and the older they are, the greater the chance of having post-herpetic neuralgia, and the more severe the pain. This neuralgia lasts for a long time, ranging from a few months to more than 10 years, making it unbearable for patients. If chronic pain is not effectively treated, it can lead to depression and anxiety, reduced quality of life, and even loss of self-care, making pain one of the major killers of human health, commonly known as the “undead disease”. In the medical field, pain is considered to be the fifth most important human vital sign after inspiration, pulse, body temperature and blood pressure. Due to the severity and chronic nature of postherpetic neuralgia, it has become a major problem that affects the quality of life of our patients, especially our elderly friends. Therefore, we should not only be concerned about the visible “herpes” on our skin, but also about the nerve fibers under the skin that are being eaten and destroyed by the virus. If the inflammation on the nerve fibers is not effectively controlled during the acute phase to protect the nerves, then over a period of 3-4 weeks, the nerve fibers may become significantly damaged and eventually degenerate, atrophy and necrotic, leading to post-herpetic neuralgia. Herpes zoster-related neuralgia is insensitive to many medications and is very tricky to treat, and the various treatment options currently available are not very effective. Especially in the early stages, if the focus is only on being able to control the attack of the virus, or if the reliance on pain medication alone is not effective in protecting the nerves from further viral attack, the effectiveness is very limited. Postherpetic neuralgia is a worldwide problem, and despite recent advances in neurobiological research, clinical treatment is not yet satisfactory. Sensory nerve fiber function testing – determining the degree of nerve damage We perform quantitative sensory nerve testing for herpes zoster-associated neuralgia and diabetic peripheral neuropathy to assess nerves that have been attacked by the virus in order to distinguish the functional status of different types of nerve fibers. The degree of nerve damage is determined and the outcome is evaluated. Herpes zoster-associated neuralgia special rehabilitation treatment For nerve damage caused by the herpes zoster virus, our treatment strategy is to focus on the damaged nerve. We focus on the nerves that have been attacked by the virus from the onset of herpes. Early antiviral and nerve protection go hand in hand to control the viral attack as early as possible so that the herpes subsides as soon as possible, while neurotrophic drugs are used to counter the inflammatory response of the nerve fibers, protect the nerves and reduce the viral attack on them. In the later stage, for the remaining neuralgia, treatment is carried out from the perspective of nourishing nerves, promoting damaged nerve repair, and regulating nerve function, focusing on promoting damaged nerve repair rather than just pain relief.
