Lower leg swelling may indicate heart disease

Swelling in the legs, ankles, or feet could be a warning sign of congestive heart failure, a long-term condition where the heart can't pump blood well enough for a normal supply. This happens when one or both of the heart's lower chambers stop pumping blood properly, causing blood flow to slow and back up in the veins in the legs, ankles, and feet, leading to edema. Early signs of peripheral edema include feeling full or heavy legs, swollen feet and lower legs, tight and uncomfortable socks, and leaving a dent when pressing the swollen skin. It is important to consult a doctor for proper diagnosis and treatment.
