Pleural adhesion and pulling pain may be considered to be related to pyothorax, malignant tumor, tuberculous pleurisy and other diseases. 1. Pseudothorax: mainly chronic pseudothorax causes pleural adhesion is more common. Chronic pyothorax can cause fibrin deposition and granulation tissue proliferation, which leads to pleural fibrosis and thickening adhesion. When the adhesion is serious, it can cause changes such as narrowing of the intercostal space and narrowing of the thorax, and it can cause pain when the lung tissues are pulled and compressed. 2. Malignant tumor: lung malignant tumor invades the pleura or primary malignant tumor of pleura, which can lead to adhesion in the pleural cavity. After the occurrence of pleural adhesion, pulling pain can occur when coughing or chest movement occurs. 3. Tuberculous pleurisy: the pleura is subjected to repeated irritation of tuberculosis bacillus, the inflammatory reaction will form fibrous strips or pleural thickening in the pleura, if the degree of disease control is not timely, or improper treatment can cause pleural adhesions, accompanied by pulling pain. Pleural adhesion with pulling pain need to go to the hospital in time to check the specific cause and treatment, so as not to delay the condition.
