Hello, My husband has been retaining water and none of the doctors that he has seen is giving us any answers to whats going on. He s been to kidney doctor, gastro doctor, heart doctor and no one seems to know. He is 49 and is diabetic. He has swollen legs, feet, scrotum, and stomach. His primary doctor started him on a water pill but its not helping been taking for a month now. Would you have any idea what this could be?
