There are many reasons for the pain during the recovery of bone fracture, such as prolonged braking, the bone has not yet recovered completely, and the local venous return is poor. 1. Prolonged braking: the affected limb is usually immobilized for a long period of time during the recovery from bone fracture, so the ligaments, fascia and joint capsule may have some adhesion, and during the recovery period, the soft tissues are pulled due to the increase of activity and functional exercise, thus pain occurs. 2. Bone quality has not been fully recovered: during the recovery period of bone fracture, especially the bone quality has not been fully recovered, there will be pain during the activities, usually there is no pain in the stationary state. 3. Poor local venous return: If the local venous return of the affected limb is poor, resulting in the obstruction of blood return and swelling, leading to the increase of tension in the interstitial space of the tissues, it will also lead to pain during the recovery of bone fracture. There are many other causes of pain during recovery from bone fracture, if the symptoms are obvious and cannot be improved for a long time, it is recommended that the patient go to the hospital in time and take standardized treatment according to the doctor’s instructions.
