This is Dr. David
I am sorry you are having water retention in your lower limbs and stomach.
have you had the heart scan yet?
does it show weakness of the heart?
you could have congestive heart failure if you have weakness of the heart causing fluid backing up in the lungs and legs.
do you have a history of congestive heart failure?
what has your blood test showed?
what do you mean you have water retention in your stomach? do you have ascities fluid in your abdomen?
