1. The most important feature of herpes zoster pain is the hemilateral pain, which is divided by the midline of the body and has distinct boundaries. This is the most obvious feature of shingles pain. 2, the older the pain, the heavier the pain: the invasion of herpes zoster is mainly for people with weaker resistance. The first is the elderly. According to international statistics, there is a very significant positive correlation between age and shingles. The older you are, the higher the incidence, the heavier the pain, and the greater the chance of residual postherpetic neuralgia. 3, latent pain is difficult to identify: the incubation period of herpes zoster varies from 3 or 4 days to more than 20 days, generally behaves like a cold, pain can occur in the head and face, neck and shoulders, chest and back, waist, lower limbs and internal organs, generally in the incubation period there is no other performance except pain, so it is easy to be confused with other diseases. Herpes in the left chest can easily be mistaken for heart disease, while herpes in the right chest is somewhat like angina radiata, but herpes pain is usually not associated with chest tightness or breath-holding symptoms. The latent pain of herpes in the lower back is easily suspected to be osteoarthritis; more serious is visceral herpes, and if the herpes involves the intestinal wall, the patient will experience flatulence, constipation, or aggravation on top of the existing constipation, and even individual patients have intestinal obstruction surgery as a result. The most unusual type is herpes zoster without herpes, where the patient does not have herpes, but all other symptoms are compatible and laboratory tests can rule out other similar diseases. Such cases are not frequent and are occasionally seen in middle-aged and older adults who usually have good resistance and no previous history of the disease. 4. Neck and shoulder herpes: the latent pain is very similar to a cervical spondylosis attack, and the pain starts from the neck and can extend along the upper limbs to the palms and fingers. In severe cases, the palms and fingers are swollen and movement is limited, but most do not have numbness. 5, pay attention to hygiene after herpes: try not to break after herpes; once broken, the exuded fluid is contagious, pay attention to disinfection for the patient’s clothes. Pay attention to open windows and ventilation to keep the room dry. Patients themselves should change their clothes and bed sheets regularly, and try to choose soft, cotton clothes. The diet should be light and easy to digest. The virus enters the body through the respiratory mucosa and is latent in the ganglion of the posterior root of the spinal cord. When the host’s cellular immune function is low, the virus is stimulated again, resulting in inflammation and necrosis of the ganglion, while the reactivated virus can move along the peripheral nerve fibers to the skin again for herpes to occur. 7. The earlier herpes zoster is treated the better (<7 days), otherwise it may produce sequelae neuralgia, the latter being more difficult to treat for abnormal pain and nociceptive hypersensitivity. The elderly in particular are prone to postherpetic neuralgia.
