I HAVE GENERALIZED 3 + PITTING EDEMA BILATERALLY TO THE LOWER EXTREMITIES, HOW CAN IT BE ELIMINATED WITHOUT DIURETIC DAILY. I STAY ON A LOW SODIUM DIET AND LOTS OF WATER. I TRY TO AVOID FATS AND SUGARS FOR THE MOST PART BUT IT DOESN'T SEEM TO SUBSIDE. ALL OF MY TEST ARE NORMAL. NO APPARENT HEART DISEASE, NO DIABETES, NO CANCERS, CHOLESTEROL IS SLIGHTLY ELEVATED. WHAT ELSE SHOULD I BE DOING TO ELIMINATE THIS?
