Coughing chest pain can be seen in a variety of diseases, such as pneumonia, pneumothorax, pleural effusion, heart failure, acute cardiac infarction, rib fracture and so on. 1. Pneumonia: In pneumonia, coughing is one of the common symptoms, local inflammation and the pulling stimulation of coughing will lead to chest pain, in addition to the patient will have fever and other symptoms. 2. Pneumothorax: In pneumothorax, coughing is one of the common symptoms due to the pressure and atrophy of lung tissues and increase of airway secretion, etc. Chest pain is mainly due to the reflex chest pain caused by the difference in air pressure. 3. Pleural effusion: a small amount of pleural effusion will cause the pleura of the dirty layer to rub against the pleura of the wall layer, resulting in chest pain, and the pleural effusion will also compress the lung tissue, leading to reflex cough. 4. Heart failure: patients with heart failure will have symptoms of chest tightness and chest pain due to the decline of heart function, and the cough is mainly caused by pulmonary stasis. 5. Acute heart attack: the common symptom of acute heart attack is pain in the anterior region of the heart, and after the heart attack, there may be pulmonary stasis that leads to coughing, or it may be due to coughing caused by taking ACEI (angiotensin-converting enzyme inhibitor) drugs such as captopril after the heart attack. 6. Rib fracture: after rib fracture, there will be localized pain of the fracture, and the fracture will lead to localized damage of the lung tissue, which will lead to coughing symptoms. In addition, gastroesophageal reflux disease, tuberculosis, lung cancer, bronchial dilatation and other diseases can also cause cough and chest pain. When the symptoms of cough and chest pain appear, you should go to the hospital in time, clarify the cause of the disease and follow the doctor’s instructions for treatment.
