"Doctor, I always feel that there is something in my throat these two days. I can't cough or swallow. Sometimes there is something, sometimes there is nothing. What's the matter?" Mr. Zhang confided to the receiving doctor in the clinic of the Otolaryngology Department of Guangzhou Red Cross Hospital. In life, we often encounter the same situation as Mr. Zhang. We always feel that something is stuck in our throat. Some people think it's a fire, and some people think it's something in our throat. So what's the matter? Liao Tao, deputy chief physician of the Department of Otolaryngology Head and Neck Surgery of Guangzhou Red Cross Hospital, said that throat is also known as throat in medicine. It always feels that there is something in the throat and there is a sense of foreign body. In medicine, this kind of disease is collectively referred to as dysphagia. In order to cope with the injury caused by various stimuli (such as sour, sweet, bitter, spicy, cold and hot), the distribution of human pharyngeal nerves is very rich, especially the nerves that control the sense, so the throat is very sensitive to the stimulation. For example, a small fishbone stuck in the throat is very uncomfortable, and if it is stuck in the buttock, it may not be so painful. Therefore, people's throat is easy to have foreign body sensation because of the proliferation of various tissues caused by various stimuli. There are three main reasons for this: 1. Pathological changes in the pharynx and its adjacent organs. When the disease involves any layer of tissue in the pharyngeal cavity or wall, the sensory nerve of the pharynx is stimulated and the nerve excitability changes, which can lead to pharyngeal alloesthesia. 2. Keep away from organ factors. When the distant organs are sick and stimulated, they can be reflected back to the pharynx via the vagus nerve and produce various abnormal sensations. It is caused by the reflex action of the vagus nerve, or it may be caused by the contraction of the pharyngeal muscles after the vagus nerve is stimulated. 3. Mental factors. Some patients who suffer from depression or trauma have a slight discomfort in the throat (such as dryness and burning sensation), are more anxious and seek medical treatment everywhere, which is mainly caused by psychological factors. Liao Tao introduced that the common diseases that cause dysphagia include the following: (1) organic diseases ① diseases of the throat itself. Inflammation, mass, tumor, scar, varicose veins and other diseases in the throat can cause dysphagia. In particular, we should pay attention to the malignant tumors of the throat, such as throat cancer, throat cancer, tongue cancer, etc., which often have no other discomfort at the beginning, and only the sense of foreign body in the throat. Therefore, we must go to a professional and regular hospital and ask a specialist to check it, otherwise it may delay the disease. Clinically, we often see patients who have been delayed by themselves. Because of lack of medical knowledge, we think that pain is not a small problem, and delay it again and again, They didn't come to see a doctor until the tumor was very large or the neck was swollen very high. As a result, it was a malignant tumor in the middle and late stage, and the curative effect and prognosis were greatly reduced. ② Disease of adjacent organs. The organs close to the throat include the nose, mouth, esophagus and neck. Diseases in these parts can also cause dysphagia. For example, dental diseases in the mouth, primary xerostomia; Sinusitis of the nose; Gastroesophageal reflux in esophageal diseases, thyroid tumors and lymph tumors in the neck. ③ Keep away from organ diseases. Suffering from certain thoracic diseases and upper abdominal diseases can also lead to dysphagia. When these thoracic or abdominal diseases are treated
