Swelling of the ankles and feet is often an early symptom of venous insufficiency, a condition in which blood inadequately moves up the veins from the legs and feet back to the heart. Normally, the veins keep blood flowing in the correct direction with the help of one-way valves.
An injury to the foot or ankle can lead to swelling. The most common cause is a sprained ankle. This happens when an injury causes the ligaments that hold the ankle in place to be stretched beyond their normal range.
