since my dad has been home from the hospital, 2 weeks ago, his feet have become very swollen, it is getting very difficult for him to walk. Now he is not drinking like he use to, and the eating is getting worse. The doctor said there is fluid in his lungs, and he has a cough. He totally forgot where the bathroom is, and the depends is not very wet. Worried about dehydration and the swelling. Is this a sign of congestive heart failure? The doctor doesnt really want us to do anything about it. She took him off his aricept and namenda and one of his blood pressure meds.
