There are several common clinical causes of rib distension on both sides of the chest: First, inadvertent falls during strenuous exercise can cause incomplete rib fractures on both sides, which can be accompanied by difficulty in breathing and restricted activity, and need to improve rib CT or X-ray examination as soon as possible. After the severity of rib fracture is confirmed, for incomplete rib fracture, external fixation of the chest strap can be used to promote faster healing of the ribs, thus reducing the symptoms of distension and pain in both ribs. Second, in patients with lung infection, there is a large amount of sputum in the lung and bronchus, which needs to be expelled by violent coughing. Repeated coughing will cause distension and discomfort on both sides of the ribs, at this time, nebulizer inhalation and anti-infection treatment can be used, and if necessary, fibrinoscopic aspiration treatment can be performed to reduce the infection in the lung and relieve the symptoms of distension and pain on both sides of the ribs in the chest.
