10. Blood Clots
Blood clots that form in the leg veins restrict the amount of blood flowing back to the heart. This causes the swelling of feet and ankles. There are two main types of blood clot conditions that affect ankles. There’s the superficial which takes place on veins just beneath the skin and the deep, known as deep-vein thrombosis. The latter is usually more severe than the former. Just like in venous insufficiency, the clots block the blood flow and cause fluid buildup in the veins around the affected area.
Blood clots are usually life-threatening and it is very crucial to immediately get treatment if having any symptoms. This is because clots can break loose and flow to the most sensitive parts of the heart and lungs. Common symptoms of blood clots include swelling of lower limbs that is accompanied by pain, fever, and the change of skin color in the affected area.
