Early cold compress: just after the injury, you need to actively apply cold compress, which can reduce bleeding, reduce local swelling symptoms, and need local protection brake, never the following activities, otherwise it will aggravate the injury, not conducive to recovery. 2. The patient should be transferred to the hospital and undergo a local X-ray examination to determine whether there is a fracture, so as to determine the corresponding treatment plan. 3. Bed rest: If a fracture is excluded, the patient should be strictly bedridden, elevate the affected limb, and actively apply some ointment to activate blood circulation and resolve blood stasis, and slowly recover. 4. Fracture repositioning treatment: If the patient has a local fracture and the fracture is significantly displaced, the patient must be repositioned.
