You can get water pills to help reduce the water retention you have at your local drug store, Just check with doc first as they may lower your blood pressure. Avoid salt and salty foods at all costs. Avoid standing and siting for long periods of time. Leg compression stockings can also help. Every chance you can… put your legs up on a pillow over the elevation of your heart.
