The turn of summer and fall is a high incidence of postherpetic neuralgia. The painful discomfort in the skin after the rash of shingles subsides and lasts for more than 1 month is called postherpetic neuralgia. It is characterized by paroxysmal or persistent burning, stabbing, throbbing, or cutting pain in the skin, which seriously affects work and life, with major changes in rest, sleep, and mental status. The incidence of herpes zoster is between 1 per 1,000-6 per 1,000 of the population, and 1/5 of these patients have severe residual neuralgia that is unbearable and seriously affects life and work. Neuralgia is the main feature of herpes zoster, caused by the virus attacking the nerve endings, which occurs before the onset of the rash or along with the rash, and is slightly milder in children and young adults and heavier in the elderly. The pain is more common in the thoracic intercostal nerve and the facial trigeminal nerve distribution. If the virus invades the corresponding brain nerve, it can affect vision, cause facial palsy and hearing impairment. It can also lead to cardiovascular and cerebrovascular pathology and even death. Post-herpetic neuralgia is characterized by anorexia and wandering, and the rash may appear elsewhere when repeated; it is heat-loving, so applying heat will aggravate the pain, so it is advisable to apply cold compresses; the pain is severe at night, so it is painful to wake up in the middle of sleep.
