10 Causes of Swollen Ankles
Reviewed: Dr. Gromatzky
Cause #6: Clots
Blood clots can form in the veins of the legs leading to the blockage of blood flow returning to the heart. This causes swelling in the lower parts of the legs such as the feet and ankles. The clots can form in superficial veins that are found just beneath the skin or in the deeper veins which is known as a condition called deep vein thrombosis.
Blood clots can break, dislodge, and travel to major organs such as the lungs and heart. If you notice that there is swelling, pain, redness, warmth, and tenderness on the affected leg, you should seek medical attention as soon as possible.
