Children’s ankle sprain recovery time should be based on the child’s degree of local sprain and the nature of the pain to judge, but also need to take a local X-ray to determine whether there is a fracture, if there is no fracture, simply just ankle ligament injury, the recovery cycle is in about 3-4 weeks. If there is no fracture, the recovery period is about 3-4 weeks. Therefore, the child is usually required to restrain the ankle within 3-4 weeks, not to walk freely, and it is recommended to elevate the lower limb, which will help the localized recovery. If the child’s localized swelling and pain have returned to normal after 3-4 weeks, he/she can do a small amount of activities with wrist and ankle protectors, if the child still has localized swelling or pain after 3-4 weeks, he/she needs to go to the hospital for a follow-up examination in a timely manner.
