One of the most common symptoms of venous reflux disease is a feeling of leg heaviness. Venous reflux disease refers to ‘leaky’ vein valves in the leg. Healthy veins return blood flow from the legs to the heart. When the valves are weak and leaky, blood will backflow or ‘reflux’ and pool in the leg veins, instead of returning up toward the heart. This increases the pressure in your legs, giving you that tired, heavy feeling. Leg heaviness tends to worsen throughout the day, especially after long periods of standing. You may notice that elevating your legs or using compression stockings reduce the symptoms of leg heaviness. Leg tiredness, fatigue, ankle swelling are other common symptoms of venous reflux disease.
