Patient: Herpes zoster appeared on the right anterior chest, right posterior back and right hand on December 20, 2009. The neuralgia has been increasing since January 3, 2010. She has been using famciclovir injection for 18 days, and taking oral carbamazepine, acyclovir tablets, and mecobalamin tablets. Now the herpes has basically fallen off, but in the past 2 weeks the neuralgia in the right side of the body has been very severe, averaging more than 10 times a day and lasting about 1 minute. I hope to be hospitalized in your hospital as soon as possible Laboratory and examination results: Doctor: Hello, herpes zoster is a nerve- and skin-loving virus that destroys nerve cells in the fifth layer of the posterior horn of the spinal cord, often forming posterior neuralgia that lasts for more than 10 years, and is a world problem in treatment. You are now in the acute phase of nerve destruction by the virus, which is the window of time for emergency neuroprotective treatment, and timely treatment can reduce the possibility of posterior neuralgia or the degree of pain.
