Nowadays, people’s work and life are very stressful, the body has been in a sub-healthy state, frequent chest tightness and chest pain. From the medical point of view, chest tightness is a subjective feeling that breathing is laborious or there is not enough air. If it is light, it is as if nothing has happened, but if it is heavy, it affects life, as if it is pressed by a stone on the chest, or even consciously have difficulty in breathing. It may be a functional manifestation of the body’s organs, or it may be one of the early symptoms of a disease that occurs in the human body. Patients may be the common symptoms of chronic bronchitis are asthma, shortness of breath, chest tightness and other obvious symptoms, when combined with respiratory infections, due to the fine bronchial mucosa congestion and edema, phlegm obstruction and narrowing of the lumen of the bronchial tubes, can produce these symptoms. Mental tension can also lead to chest tightness, mostly because of excessive stress, mental tightness, long-term depression caused by sitting or lying down will feel chest tightness, palpitations, but often do not check the results. There are some people in life who often feel their chest tightness is obvious, it is likely to be caused by heart disease. A lot of heart disease in the process of development will appear chest tightness, like common coronary heart disease, heart tumor, pulmonary heart disease and so on may trigger chest tightness. Chest tightness is obvious people need to be vigilant, it is likely to be caused by long-term heavy smoking, now many people have the behavior of smoking, long-term heavy smoking, excessive intake of harmful substances in tobacco, usually also reduces the function of the heart and lungs, the emergence of chest tightness. In addition to the above possibilities, there is another lesser known but very common cause of the condition, which is cervical spondylosis. I once heard a saddening news story about a woman who was treated for three years for cervical spondylosis as heart disease. From three years ago, Ms. Lee often feel chest tightness, panic, shortness of breath, to the hospital many times, but the heart did not find too much abnormality, and medication did not see any improvement, and then she heard that a friend got cervical spondylosis, and her symptoms are somewhat similar to the rush to find an expert examination, and indeed was diagnosed with severe cervical spondylosis. It turns out, cervical and thoracic vertebrae on the small joints are misaligned, will compress the sympathetic nerve, thus affecting the sympathetic nerves innervating the heart, resulting in sympathetic nerve disorders so that the coronary artery spasm, so that can not provide more blood to the heart to consume, which will lead to the heart’s temporary ischemia, chest tightness and heart panic. In short, chest tightness shortness of breath, always feel out of breath must be taken seriously, you should go to a professional hospital to find the cause of chest tightness, do not limit yourself to the heart, lungs and other common parts of the heart, other causes of the same may lead to chest tightness, so as to avoid delays in the best time for treatment!
