A month ago, Zhang old uncle after the cold left side of the face appeared unexplained tingling and pain like burning, a few days later the skin grew a red herpes, also did not care, asked relatives and friends that may have herpes, that is, Jiaxing words so-called “snake wrap”, although everyone said “N a N “The hospital gave him timely treatment such as hanging saline and applying ointment, and after ten days the herpes on his face grew well, so he stopped taking medicine and hanging saline. But not long after, his face became more and more painful, he thought the skin has grown, bear with it, but never thought that gradually his eyes are a little bit open, filial son and daughter brought him to Jiaxing Hospital of Traditional Chinese Medicine ophthalmology. The doctor found that there is still herpes keratitis, continue to be admitted to the hospital, a few days later the condition gradually stabilized, eye discomfort is also significantly better, but the forehead and left face pain is still very intense, can not sleep at night, eating is also affected, Zhang old man has always wondered why the skin herpes is better, how this pain is always better still so powerful? The attending ophthalmologist promptly asked the pain department for a consultation, and after careful examination, Director Zhu Bo confirmed that Zhang was suffering from herpes zoster neuralgia on his head and face. He explained to Zhang and his son that the fundamental problem of herpes zoster is not the skin, but the nerve that the virus has invaded. The nerve is like an electric wire, and when the virus breaks the plastic skin on the outside, the electricity leaks and it is very painful. The layman’s explanation helped Zhang understand the reason. After a nerve block treatment to block the pain and nourish the nerve, Zhang was discharged that night with his first good night’s sleep in a month. 2 days later, he was treated with minimally invasive radiofrequency pulse surgery under ultrasound guidance again to reduce the sensitivity of the nerve to pain, combined with internal Chinese medicine and meridian physiotherapy for a week. The pain department of Jiaxing Hospital, Dr. Zhu Bo, director of the Department of Pain, Jiaxing, the so-called “snake wrapped”, that is, infected with chickenpox-herpes zoster virus, it is mostly infected in childhood, chickenpox healed, the body is still a small amount of virus hosted in the spinal ganglia in a latent state, when the body’s cellular immune function is reduced in the latent virus in the ganglia again be When the body’s immune function is reduced, the virus in the ganglion is activated again and causes herpes zoster. Therefore, herpes zoster itself is a disease in which the virus invades the nerves and causes inflammation or necrosis, causing pain in the corresponding area; when the virus moves along the nerves to the skin, it produces segmental blisters on the skin that are characteristic of herpes zoster. The skin blisters generally heal easily, while the ganglia, etc., invaded by the virus are not easily repaired, especially in the elderly, in people with poor immunity and in patients with tumors. Generally we most commonly see herpes zoster on the chest and waist, while old man Zhang suffers from head and facial herpes zoster, which is relatively rare, may be more painful and difficult to treat. Dr. Zhu Bo, the chief doctor, once again warned patients that patients with herpes zoster pain should seize two key time periods for treatment, within one month and within three months. The damaged nerve may be repaired by various methods including anti-viral, nerve nourishing medication, nerve block treatment near the affected nerve root and interventional treatment such as minimally invasive radiofrequency, combined with oral Chinese medicine, otherwise it will be more difficult. Pain is also a sign of nerve recovery. According to foreign literature, the more severe the pain after herpes zoster, the greater the possibility of post-herpetic neuralgia. Once the pain is more than three months, the diagnosis of post-herpetic neuralgia often requires long-term oral medication, or even minimally invasive interventions such as intraspinal spinal cord electrical stimulation and intrathecal drug pump implantation, which are very expensive. Therefore, if you have this disease, you must treat it early and regularly, and never believe in native methods. The pain needs to be treated in a timely manner and should not be tolerated in the acute phase, which can lead to post-acute neuralgia. At the same time the diet can be appropriate to eat more such as strawberries, blackberries, cherries, apples, oranges, bananas, etc.. Bananas also have pantothenic acid, which is the body’s “happy hormone”, can reduce psychological stress, relieve tension, depression and other emotions, eat bananas before bedtime has a sedative effect. During the treatment period, patients are forbidden to eat spicy and warm food, such as tobacco and alcohol, ginger, chili, mutton, beef, etc. Drink more water and drink silver flower and comfrey tea. The food therapy can be eaten diamond congee, stir-fried shredded pork with amaranth, lotus seeds, red beans, poria soup, etc. is beneficial to promote recovery.
