Three-dimensional CT of a rib injury did not show a fracture, but it hurts when I cough, considering a soft tissue injury or bone contusion in the chest. If a rib injury does not show a fracture on 3-D CT but is painful when breathing deeply, coughing, sneezing, or turning or bending over, consider that there may be a soft tissue injury or bone contusion in the chest. Even if there is no fracture, localized hematoma or intercostal muscle strain, intercostal nerve injury, or rib contusion will also have pain and other related symptoms. It is recommended to treat the specific injury accordingly. Therefore, even if there is no fracture in the 3D CT examination after rib injury, as long as there are symptoms of pain in both chests, it is recommended to consult a doctor in time and take therapeutic measures under the doctor’s guidance, which should not be taken lightly so as not to cause any delay in the condition.
