You are the mother of 3 you cannot give up. They need YOU! Have your doctors put you on a simple water pill. I have horrible edema, if I don't take my water pill I will gain 10 pounds of fluid on my legs and feet overnight. It took about 2 weeks for the excess to go away but as long as I take that pill every morning I don't get it at all until the week of my period. Nothing seems to help me then. Hang in there and keep fighting.
