The symptoms of bruising and swelling after a fracture will slowly disappear after about 1-2 weeks of active treatment and will recover completely in about 1 month. These symptoms are mainly caused by contusion of the surrounding tissues after the fracture and bleeding caused by the fracture itself, so it is recommended to apply cold compresses within the first 24 hours after the fracture to reduce the degree of bruising and swelling. After 24 hours, it is recommended to apply local heat to promote blood circulation and reduce swelling.
