Herpes zoster neuralgia can be difficult to treat. Generally, when the symptoms are mild in the early stage, you can take oral medication, mainly some nerve-nourishing drugs, and drugs to relieve nerve pain, such as carbamazepine and gabapentin. However, in some patients, the pain is so severe that the problem cannot be solved by drugs alone. One of the ways is to destroy the nerve, using radiofrequency electrodes or injecting drugs to destroy the damaged nerve, and in some cases, the nerve is even cut out, so that the nerve no longer transmits pain signals, but the corresponding nerve function is also lost. Therefore, before surgery, it is necessary to evaluate whether the damaged nerve performs an important function and weigh the pros and cons. If destroying the nerve would result in the loss of important functions, then this method is not suitable; if destroying the nerve would result in the loss of some sensory function, but would have little impact on the patient’s life, then it could still be used. Since this method does not solve the pain of all patients suffering from neuralgia, is it possible to prevent neuralgia in advance? In fact, if the patient is acutely infected with varicella-zoster virus, most of the time the rash appears first and then the neuralgia occurs, then we should not only inject antiviral drugs into the local skin when the rash appears to prevent the virus from “drilling” into the nerve roots along the nerve fibers in time to prevent neuralgia, but also push back through the site of the rash to the nerve roots that have suffered erosion. At the same time, the nerve roots that have suffered erosion are retrograded through the site of the rash, and drugs are injected locally into the nerve roots to eliminate inflammation and repair the nerves, avoiding adhesions and further damage. This is nerve block treatment, which is usually performed in the outpatient clinic after examination and evaluation. After the treatment is done, stay and observe for 10~30 minutes, and you can go home and rest if there is no abnormal reaction. However, if the patient’s blood pressure is not well controlled, blood sugar is relatively high, and he/she is not in good health, he/she needs to be hospitalized first to adjust and stabilize before treatment. This nerve block treatment is usually done 3~5 times with an interval of 3~5 days each time. More than 90% of patients treated within one month after the onset of the disease will have better results; however, if treated after one month, the improvement rate drops to 80%, and if treated after two months, the improvement rate drops to 70%. If the patient does not receive treatment until the nerve pain appears, or if the nerve pain does not appear until he has been infected with the virus and his immunity is reduced, it means that the nerve has been more seriously damaged, and the treatment effect in this case will not be too good. If the pain is recurrent and cannot be cured by medication and nerve block is not effective, an external “pain pump” should be installed at the corresponding nerve root, which contains pain medication and is implanted into the nerve root through a thin catheter, so that when the patient feels pain, a certain amount of pain medication can be pumped in to directly and effectively stop the pain. pain relief. It usually needs to be placed for 1 to 2 weeks, depending on whether the patient’s pain is relieved or even disappears. In conclusion, the treatment of nerve pain is not that simple, and the most crucial thing is to detect and deal with it early, and not to wait until it really hurts before you get anxious.
