Pleural adhesion is the adhesion of the dirty pleura and the wall pleura to each other due to infection, trauma, etc. In the early stage of pleural adhesion, there are usually no conscious symptoms, but in more serious cases, chest pain, hemoptysis, and dyspnea may occur. As patients suffer from pneumonia, tuberculosis, pleurisy and chest injury, the pleural cavity will usually ooze out fluid, and the fibrin in the fluid adheres to the pleura, thus causing two layers of pleural adhesions. In the early stage of pleural adhesion, there are usually no conscious symptoms, so if chest pain, hemoptysis, dyspnea, accompanied by fatigue, palpitations and other symptoms, it means that pleural adhesion is more serious, and you need to go to the hospital for treatment in a timely manner. If pleural adhesion occurs, it is recommended to go to the hospital in time to find out the cause of the disease, under the guidance of the doctor, to carry out targeted treatment.
