Pharyngeal heterosensitivity is a very common symptom, which often refers to various abnormal sensations in the pharynx other than pain, and is called “plum kernel gas” in Chinese medicine. Because the nerves in the pharynx are very rich, resulting in diseases of many organs in the body can cause abnormal sensations in the pharynx, and brain dysfunction can also cause abnormal sensations in the pharynx. The common causes are: 1) diseases of the pharynx 2) diseases of the organs adjacent to the pharynx 3) diseases of distant organs. The diseases of distant organs are the most complicated and difficult to determine. Common distant organ diseases include gastrointestinal diseases, cardiovascular diseases, respiratory diseases and ophthalmic diseases. 4.Systemic factors, common systemic factors include iron deficiency anemia, autonomic dysfunction, dyspepsia, malignant tumors, gynecological diseases, gout, myasthenia gravis, hypothyroidism, endocrine disorders 5.Psychiatric factors and functional disorders. Mainly, brain dysfunction is often accompanied by anxiety, impatience and tension, and there is a fear of cancer. In one case, due to pharyngeal heterosensitivity, all the examinations that could be done, including Pate CT, were done, and no problem could be found at that time, but bile duct cancer was still found after a year, and the days were not long after the discovery. The reason is that Patek CT is not sensitive to GI tumors. And this cholangiocarcinoma could not be detected until the advanced stage. Therefore, it is very difficult to find the cause of this symptom of pharyngeal heterosensitivity, and ENT consultation can only initially exclude that there is no organic disease in the throat. But to rule out lesions in other parts of the body is an impossible task for doctors. Even if the patient is willing to pour money into the examination, but the development of medicine still has a lot of unknowns, even if the thought of the disease, some early detection is not, and now the medical environment is not very good, so most doctors are very headache for this disease, can only be treated according to the possibility of disease, the so-called science is not absolutely perfect, but also no way to approach. If the patient wants an absolute conclusion, the doctor can only say that there is no absolute certainty, but he can say that 99% of you do not have cancer, if you must exclude that one percent, it is recommended that you look at several more doctors, because different doctors will have different findings, it is easier to find the real cause and the treatment is more likely to take effect.
