My dad is 87 and has CHF, dementia and Neurapthy. He was just in the hospital to have fluid drain off of his body. Prior to this, he had an extremely bad cough and was coughing up stuff (normally white looking phlem). We got him home yesterday and already his legs are starting to swell back up with fluid. He refuses to take lasix or any other water pill. Right now, his coughing is better but I know it will get worse again. What things do I need to pay attention to when his legs get extremly swollen again and the coughing gets bad again?
