Swelling after ankle sprain can be treated by the following methods: First, elevate the affected limb: elevate the affected limb as much as possible to make use of the effect of gravity to eliminate swelling quickly, and also cooperate with the active flexion and extension activities of the toes to speed up the swelling. Second, local treatment: continuous local cold compress treatment, instead of hot compress treatment, can make the blood vessel contraction, so that the swelling quickly decreases, after the swelling is obviously relieved to hot compress treatment, the effect is better. Third, fix the joint: the affected limb can be fixed with a brace, but not with an elastic bandage with pressure. Since swelling has already occurred, using an elastic bandage will further aggravate the swelling, and using a brace to fix can protect the ligaments and articular cartilage of the ankle joint to avoid aggravating the injury. Treatment through the above methods can bring quick relief to the swelling symptoms after ankle sprain. You should also pay attention to protecting the ankle joint, especially when going down steps, to avoid spraining the ankle joint.
