Chest pain due to chest expansion

Most people work in front of computers every day and sit all day long. As a result, this group of people lack exercise. Occasionally, they feel some pain when doing chest expansion exercises. It is not common to feel cracking pain in the chest when doing chest expansion. Individuals should also pay attention to the amplitude when doing exercise. If it hurts a lot, they should pay attention to whether pleurisy has occurred. In addition to chest pain, pleurisy may also cause cough, fever, etc.

What is the pleura?

The pleura is a membrane located between the lungs and the chest wall. It consists of two layers, the outer layer is the parietal pleura and the inner layer is the visceral pleura. The closed space surrounded by the inner and outer layers of pleura is the pleural cavity. Under normal circumstances, the two layers of pleura are closely attached, and there is a small amount of physiological fluid (about

0.3ml/kg body weight) acts as a lubricant. Since the pleura and pleural cavity of a normal person are not directly connected to the outside world, pathogenic microorganisms from the outside world cannot directly contact the pleura and cause disease. The pathogenic factors often invade the pleura through the lungs and cause disease. Therefore, the occurrence of pleural diseases is often related to lung diseases. What is pleurisy? Pleurisy is an inflammatory change in the pleura caused by various reasons. Common causes include: tuberculosis, pneumonia, pulmonary infarction, lung cancer, metastatic cancer, pleural mesothelioma, rheumatoid arthritis, systemic lupus erythematosus, parasitic infection (such as amebiasis), pancreatitis, injury (such as rib fractures), drug allergic reaction (such as hydralazine, procainamide, isoniazid, phenytoin, chlorpromazine), abnormal lipid metabolism, etc. Do many people suffer from pleurisy? Pleurisy is not a rare disease. The most common type of pleurisy is tuberculous pleurisy.

What types of pleurisy are there? According to the different causes of pleurisy, pleurisy can be divided into: tuberculous pleurisy, parapneumonic pleural effusion, purulent pleurisy, tumor pleurisy, connective tissue disease pleurisy, fungal pleurisy, cholesterol pleurisy, traumatic pleurisy, etc.

Depending on whether there is fluid accumulation in the chest cavity, pleurisy can be divided into: exudative pleurisy (with fluid accumulation) and dry pleurisy (without fluid accumulation).

What symptoms may occur if you have pleurisy?

Common symptoms of pleurisy include chest pain, difficulty breathing, cough, fever, etc. (1) Chest pain: It is usually a stabbing pain, most obvious on the side of the chest. It is caused by the friction between the inner and outer layers of the pleura. The pain may be aggravated by coughing and deep breathing, and may be relieved by lying on the painful side. The pain can also radiate to the ipsilateral shoulder and upper abdomen. Chest pain may be relieved when pleural effusion occurs. (2) Dyspnea: Dyspnea refers to the feeling of lack of air and difficulty breathing. Both exudative pleurisy and dry pleurisy can present with dyspnea. 1) Exudative pleurisy: When a large amount of fluid accumulates in the chest cavity, it will hinder the expansion of the lungs, causing difficulty breathing, accompanied by symptoms such as chest tightness, shortness of breath, and palpitations. Patients with large amounts of pleural effusion may even have difficulty lying flat and are forced to breathe in a sitting position, with their faces turning cyanotic due to lack of oxygen. 2) Dry pleurisy: Since deep breathing will aggravate the pain, patients often dare not breathe hard, resulting in shallow and rapid breathing, and both inhalation and exhalation feel strenuous.
