The presence of stabbing pain during the fracture recovery period should be considered for the following reasons: first, caused by the soft tissue injury caused by the fracture. When a fracture occurs, the fracture break end will produce stabbing injury to the soft tissue and cause bleeding in the soft tissue, so during the first month of the fracture healing period, there may be pain in the soft tissue, which is normal. Secondly, consider that the fracture is fixed and then displaced, such as when the fracture is fixed in a cast, due to the loosening of the cast, or the patient does not strictly follow the medical advice and walks on the ground in advance, so that there will be another load on the fracture, which will cause the fracture broken end to move slightly or even move, which will also stimulate the local soft tissues and cause the stabbing pain.
