For nerve block treatment of herpes zoster neuralgia, in order to avoid infection of the injection site, it is best not to get wet and not to take a shower for 48 hours; in addition, keep the skin of the rash area where the herpes is growing dry, try not to break it, and do not apply topical medication casually. After the injection treatment, generally bending down and lying down is no problem, try to rest, do not work too hard, do not do sports, wait for the rash on the skin crust, completely well before sports. Some people get a little dizzy after the injection, but they usually get better after resting for a while. Since the treatment site is determined by accurate evaluation and the treatment is only for the local nerve, the possibility of damaging other surrounding nerve tissues is very small. In addition, along with local treatment, to ensure effective pain relief, patients need to use pain medication, such as carbamazepine and gabapentin, which are pain medications that generally do not cause drug dependence and do not need to worry about addiction. Moreover, painkillers must be taken according to medical advice, not when it hurts to eat, not when it hurts to eat, so the pain relief effect is not good. If you take painkillers after a certain course of treatment, the effect of pain relief is better, no more pain, then you can consider starting to stop the drug. Generally, the dosage is slowly reduced to a very small dose and then no more pain, so you can stop the medication completely. If the effect of taking painkillers is not good, it means that the patient is not sensitive to such painkillers and should switch to other methods of pain relief.
