Thank you! I am a caretaker for my father in law. He is 88years old and is currently taking lasix for fluid retention. He was so bad that the fluid was restricting his breathing....He's been on it about 1 1/2 weeks now, but I think he should be losing the fluid faster.... that's the 1st issue, the 2nd is that he says his penis is swollen also and sometimes hurts to pee, but he feels like he can't get enough out....
