After detailed examination, Mr. Wang did not have obvious symptoms of coronary heart disease such as arrhythmia and asthma. In addition, the author has been his family doctor for many years and knows that his family has no history of heart disease. Instead, he found a row of rashes and blisters near his chest , Mr. Wang said that the affected area was tingling and itchy, and he believed that these rashes were the main cause of the "heart pain". "Mr. Wang, based on your current symptoms, it looks like a 'raw snake'!" He immediately breathed a sigh of relief.<\/p>\n\n\n\n
In medicine, "raw snake" means suffering from shingles, which is a disease caused by Varicella Zoster Virus (VZV). The most obvious symptoms are rashes and blisters arranged in bands along the spinal nerves on the skin of the patients. Because most of the cases only involve one side of the nerves, most cases only affect one side of the body. If the patient feels pain on one side of the chest, accompanied by the above symptoms, it may be secondary pain caused by the herpes zoster virus.<\/p>\n\n\n\n
Why is there a snake? Herpes zoster is not directly transmitted, but itself is a complication of chickenpox. When the human body is infected with the varicella zoster virus, chickenpox will develop, and after the chickenpox is cured, the virus will remain dormant in the human nervous system; when lack of sleep, excessive stress, and weakened immune system, the virus will have a chance to become active again, causing "Raw Snake".<\/p>\n\n\n\n
The varicella-zoster virus is contagious. If you have never had chickenpox and have no antibodies against chickenpox, you may be infected with the varicella-zoster virus through contact with the blister fluid of a patient with chickenpox or "raw snake", resulting in chickenpox. There is a chance Herpes zoster develops after the virus has been dormant for many years.<\/p>\n\n\n\n
An earlier study in the United States found that people who have been infected with the new coronavirus have a 15% higher risk of "raw snake" than those who have not been infected with the new coronavirus. Because after being infected with the new coronavirus, the immune system will be in a state of transient imbalance, and the number of T lymphocytes in the body will be low, which will weaken the body's immunity. At this time, the latent varicella zoster virus in the body can easily take advantage of it.<\/p>\n\n\n\n
Although Mr. Wang mistakenly thought that he had a heart problem and sought medical treatment, this time it can be said that "there was a mistake." Because 72 hours after the onset of herpes zoster is the golden time for treatment, taking the antiviral drugs prescribed by the doctor during this period can help alleviate the condition, reduce the degree of acute pain and "post-herpetic neuralgia". In addition, applying topical ointment on the affected area can help relieve the pain of the rash and speed up the scab formation of the blisters, so as to prevent the wounds from being damaged and infected with bacteria.<\/p>\n\n\n\n
Herpes zoster can cause severe and persistent postherpetic neuralgia, and some cases have been troubled by pain for a long time after recovery. In addition to skin and postherpetic neuralgia, it may also cause rare sequelae such as meningitis and pneumonia. In some patients, the eye branch of the trigeminal nerve "snakes" and affects vision. In severe cases, it may even lead to blindness.<\/p>\n\n\n\n
Many elders also asked whether the "snake needle" is effective? Getting vaccinated against shingles is indeed an effective way to prevent raw snakes. As the age increases, the incidence rate will increase accordingly. It is generally recommended that people over the age of 50 be vaccinated, which will help reduce acute infection and sequelae of pain.<\/p>\n\n\n\n
However, it should be noted that vaccination is only of a preventive nature, not for treatment. Patients who are currently "snakes" are not suitable for vaccination. It is recommended that after recovery, consult your doctor when it is appropriate to vaccinate.<\/p>\n\n\n\n
When he found out that it was a "raw snake", Mr. Wang asked the doctor suspiciously: "There are rumors that if a "raw snake" surrounds the body, there is a risk of death. Is it true?" The answer is of course not true. Woolen cloth! Because the human nerve line is distributed from each section of the spinal cord in the middle of the back to the left and right. The virus is distributed along a nerve line, and it is generally impossible to connect the left and right nerve lines to form a circle. The cases where the nerve lines on both sides are distributed at the same time are rare. If such a situation shows that the patient's immunity is weak, it is necessary to seek medical treatment as soon as possible to find out the cause.<\/p>\n\n\n\n
