The swelling of bones after trauma is mainly caused by soft tissue edema, hemorrhage and bleeding from periosteal injury. After this situation, we must limit the activities of the injured bone and apply cold compresses within 24 hours of the injury to reduce the pain and to relieve the swelling. After 24 hours, the swollen area can be treated with external blood circulation and oral medication to promote blood circulation, thus promoting the swelling to subside. 48 hours later, hot compress treatment can be performed to promote local blood circulation, thus promoting the absorption of blood edema, which will promote the recovery of swollen bones. However, it is important to avoid excessive weight-bearing activities and repeated flexion and extension of the limb within two weeks to avoid aggravating the swelling and slowing down the recovery.
