First of all, you should avoid continuing to bear weight or walk after the injury, and avoid having your companions massage the injured area.

You can use a bandage or wide tape to bandage and fix the affected ankle in a mild valgus position after 90 degree dorsiflexion, restrict walking, and send it to the hospital for treatment.

Second, for those with mild symptoms, cold water or cold towel can be used for external application and the affected limb can be elevated immediately after the injury. At this time, cold compress can constrict blood vessels, reduce local congestion, lower tissue temperature, and play a role in stopping bleeding, reducing swelling, and analgesic. Therefore, after an acute sprain, local cold compress should be applied, and the sooner the better. Elevating the affected limb can speed up the return of blood and lymph fluid and prevent blood from accumulating in the injured part of the blood vessel.

Cold compress method: Place a towel soaked in cold water on the injured area and replace it every 3 minutes or so. You can also put ice cubes in a plastic bag for external application, 20 to 30 minutes each time. In summer, tap water can be used for flushing. The flushing time is generally about 4 to 5 minutes and should not be too long.

Third, if the ankle sprain has lasted for more than 24 hours, hot compress therapy should be used instead. At this time, hot compress can improve blood and lymph circulation, which is beneficial to the absorption of congestion and exudate in the injured area.

Hot compress method: Place a towel soaked in hot water or hot vinegar on the injured area, and replace it after 5 to 10 minutes when the towel no longer feels hot. Do it 1 to 2 times a day, and apply hot compress for about 30 minutes each time.

After a joint sprain, it should be treated promptly. The principle is to immobilize and reduce swelling and blood stasis, so that the damaged tissue can be well repaired. If there is a lot of hemarthrosis, it should be removed in time under aseptic techniques to avoid subsequent intra-articular adhesions. Those with ligament rupture or avulsion fractures that affect joint stability require surgical reduction and repair to avoid repeated sprains, articular cartilage damage and traumatic arthritis.
