The rib has suffered a fracture. Depending on the displacement of the fracture, whether it's a single rib or multiple ribs in multiple locations, and whether breathing is affected or there is a presence of blood or fluid in the chest cavity, a comprehensive analysis is required. If the fracture is a single rib or multiple ribs with hairline fractures, it is possible to move around, but rest is also important to avoid turning a stable fracture into one with significant displacement. If there are fractures in multiple ribs at multiple locations and a large amount of blood or fluid in the chest cavity, along with flail chest that significantly impacts breathing, it is not recommended to continue activities. Rest should be prioritized, and, if necessary, joint cavity puncture drainage may be performed to relieve symptoms.
