Your circulatory system consists of blood vessels that deliver blood throughout the body. Blood keeps your body healthy and functioning. It transports oxygen and nutrients to your tissues and eliminates carbon dioxide and waste. Given the importance of blood, poor circulation can lead to serious health problems.
Poor circulation in your feet and lower extremities occurs because of compromised blood vessels that serve those regions. Common symptoms of poor circulation in the legs and feet include numbness, muscle cramps, and cold feet.
