First of all, you should avoid carrying heavy loads or walking after the injury, and avoid being rubbed by your peers in the local area of the injury.

You can use a bandage or a wide adhesive tape to bind and fix the ankle of the affected side with a slight eversion after 9-degree dorsiflexion, so as to restrict walking and send it to the hospital for treatment.

Second, for those with mild symptoms, cold water or cold towel can be applied externally after the injury and the affected limb can be raised. At this time, cold compress can make blood vessels contract, reduce local congestion, lower tissue temperature, and play a role in hemostasis, detumescence and analgesia. Therefore, after acute sprain, local cold compress should be applied, and the sooner the better. Raising the affected limb can speed up the return of blood and lymph, so as not to cause blood stasis in the vascular injury.

cold compress method: put the towel soaked in cold water on the injured part and change it every 3 minutes or so, or put it in a plastic bag with ice cubes for external application for 2-3 minutes each time. In summer, tap water can be used for washing, and the washing time is generally about 4 ~ 5 minutes, which should not be too long.

Third, if the ankle sprain has been more than 24 hours, you should switch to hot compress therapy. At this time, hot compress can improve the circulation of blood and lymph, which is beneficial to the absorption of congestion and exudate in the wound.

hot compress method: put the towel soaked in hot water or hot vinegar on the wound, and replace it after 5-1 minutes when the towel has no heat sensation. It is carried out once or twice a day, and each hot compress is about 3 minutes.

After joint sprain, it should be treated in time, and the principle is braking, detumescence and removing blood stasis, so that the damaged tissue can be well repaired. Those with excessive joint hemorrhage should be pulled out in time under aseptic technique to avoid intra-articular adhesion. If ligament rupture or avulsion fracture affects joint stability, surgical reduction and repair are needed to avoid repeated sprain, articular cartilage injury and traumatic arthritis.
