Edema has many possible causes: 1  Prolonged standing or sitting, especially in hot weather, can cause excess fluid to accumulate in the feet, ankles and lower legs. 2  Tiny valves inside the veins of the legs can become weakened, causing a common problem called venous insufficiency.
Some conditions that may cause swelling in just one leg include: 1  Blood clots. Clots can cause pooling of fluid and may be accompanied by discoloration and pain. 2  Weakened veins. Varicose veins, or veins whose walls or valves are weak, can allow blood to pool in the legs. 3  Infection and inflammation.
