Swelling on both legs and feet is an indication of fluid accumulation, which can be a symptom of heart failure. Fluid tends to build up when there is a reduced flow of blood from the heart, which causes the blood going back to the heart to get backed up and congested. The swelling usually worsens late in the day. If you notice any kind of swelling on your legs and ankles, see your doctor for assistance.
