Hi and welcome. Thank you for your query. Swollen ankles and swollen feet are common and usually not cause for concern, particularly if you have been standing or walking a lot. But feet andankles that stay swollen or are accompanied by other symptoms could signal a serious health problem. An injury to the foot or ankle can lead to swelling. The most common is a sprained ankle, which occurs when an injury or misstep causes the ligaments that hold the ankle in place to be stretched beyond their normal range. To reduce the swelling from a foot or ankle injury, rest to avoid walking on the injured ankle or foot, use ice packs, wrap the foot or ankle with compression bandage, and elevate the foot on a stool or pillow. If swelling and pain is severe or doesn t improve with home treatment, see your doctor.
