•CHF?•••••CHF would cause bilateral pedal edema. Based on what you have told me, which isn't very much, it is more likely due to an obstruction in the lymphatics or venous system of the left leg, which could be due to a number of things. It's probably just something as simple as you are sleeping in an odd position that cuts off circulation to your left foot, or you are not getting enough activity in your left foot. If it doesn't go away after a while, you would need to be medically evaluated.
