Leaving aside the concept of disease, the patient’s simple chest pain is just a symptom, a sensory response. If general anesthesia were administered, would the patient still feel pain? Can we then say that the patient is cured? The ibuprofen taken by the patient has the same effect, it is a relatively common analgesic drugs in the clinic, under the premise of ignoring its side effects, can be used without probing the patient’s condition, the patient’s chest pain is extremely probable, but in the ibuprofen’s efficacy, was covered up and hidden, in this case, we can’t make any judgment of the patient’s condition, it is also very difficult to give professional advice, the only thing we know is that is: left anterior chest pain! However, limited by the degree of medical knowledge, the left anterior chest pain described in the patient’s mouth, there may be errors, perhaps the patient’s perception is wrong, the description is wrong, there may be radiating pain and so on, radiating pain is to say that the lesion is not in the left chest, may be in the cervical, thoracic, lumbar spinal cord centers or in a large nerve center or nerve cadre position. If the patient’s description is correct, then we look at the possibility of causing chest pain? First, heart disease myocardial infarction, angina pectoris, rupture of the aortic dissection will make the left chest pain, this pain is tearing, knife-cutting pain, this situation we need to go to the cardiology department as soon as possible, so as not to delay treatment. Second, lung disease lung disease affects the pleura or compression to the nerve chest pain, so the pain is not very obvious, if it is a chronic cough for more than three weeks, only began to feel chest pain, can be considered for lung disease. Third, stomach diseases Gastroesophageal reflux is a common cause of chest pain, it is easy to confuse it with chest pain caused by heart disease, if the chest pain improves after burping, or sour taste in the mouth, then it is likely to be caused by esophageal reflux. Fourth, muscle strain chest muscles because of incorrect posture, sports injuries and strains, it may cause chest pain, but this pain entity table pain, will change with the posture will make the pain more painful place. Fifth, autonomic nervous disorders autonomic nervous disorders will appear similar to angina chest pain, this symptom taking nitroglycerin can not be relieved, resulting in this autonomic nervous disorders with our daily work pressure, tension, anxiety and other factors closely related to the state of mind. Six, cervicothoracic spine lesions when we cervicothoracic spine lesions, will make the cervical sympathetic nerves, vertebral peripheral nerves are compressed, resulting in nerve disorders excitation, nerve disorders excitation will make the blood vessel spasms and contractions, resulting in cardiac ischemia ischemia and hypoxia so that the left chest pain. Network to see the doctor is already very difficult, if there is no detailed description of the condition, it is more difficult to diagnose, if the patient really want to judge their own disease, but also need to give a detailed account of the age, medical history, triggers, nature and related checks, so that a comprehensive consideration can be carried out, and with the right starting point to reach the finish line.
