The ankle sprain is still swollen in January. In this case, it is important to reduce the frequency and duration of weight-bearing walking and to perform an MRI review of the ankle joint to clarify whether there is an ankle ligament tear. If there is an ankle ligament injury, an elastic bandage can be used for fixation, which will increase the stability of the ankle joint and reduce the chances of swelling. If the MRI reveals a complete tear of the ankle ligaments, along with instability of the ankle joint, surgery is recommended to restore the stability of the joint and rebuild the integrity of the ligaments so that the swelling can be completely eliminated.
