Swollen ankle sprains in toddlers can be treated by resting the affected limb, ice, compression, and elevation of the affected limb. Sprained ankles in young children should reduce the ankle joint activities, preferably lying in bed for rest. If the sprain continues to move, it can lead to aggravation of the joint damage, and is not conducive to the prognosis of the disease. Within 72 hours after the sprain, you can apply local ice packs or rinse the affected ankle joint with cold water, and then apply local heat packs after 72 hours. Until fully recovered, avoid excessive movement and exercise of the injured area. Ankle sprains can also be compressed with an elastic bandage, which reduces swelling and localized bleeding. In addition, compression itself is beneficial in restoring stability to the ankle joint. After an ankle sprain, try to elevate the affected foot above the level of the heart while resting. Elevating the affected limb speeds up venous return and reduces the symptoms of swelling in the affected limb. If the symptoms continue to worsen after ankle sprain, you should seek medical treatment in time. Pay attention to rest on weekdays, avoid strenuous exercise, maintain regular hygiene and avoid secondary infection.
