Elevate/evaluation: If the swelling is painful, or if your hand is cold, pale, or numb, you need to be evaluated promptly. If your arm is in a cast, it's possible the cast was placed too tightly and is cutting off venous blood flow. If there is no pain, pallor, or numbness, then keeping your hand elevated above the level of your heart will help reduce the swelling.
