No pain without moving is not necessarily a fracture, but may also be a simple soft tissue injury, as follows: a. A simple soft tissue injury will show painful symptoms when the patient is active, while resting and braking painful symptoms will disappear completely, and there will be significant local swelling and even subcutaneous bruising; b. When a fracture occurs, the patient’s painful symptoms are more intense when moving, while the fracture end remains stable after resting and braking, and the periosteum nerves will not be significantly stimulated. At this time, there can be no pain symptoms, especially incomplete fractures, such as fracture of the cleft and green branch fracture. Therefore, it is not possible to judge whether a fracture has occurred based on pain and activity, but must be further confirmed with reference to radiographs, which will show a discontinuity in the bone cortex and interruption of bone integrity when a fracture occurs.
