Hi doctor, My dad is 83 years old. He keeps coughing up phlegm and sleeping all the time. He is cold and his feet are very swollen. His feet are so puffy and he feels difficult to wear shoes or walk. He weighs about 300 lbs. He is suffering from congestive heart failure. Currently, he is on Lisinopril for blood pressure, Potassium supplement and Furosemide for water retention and Cetirizine for allergy symptoms.
