<s>[INST] I have water in the lungs according to my doctor. He has put me on a water pill. He told me this would help my cough. But I have been coughing all day and sometimes it feels like I cannot breathe. Also when I eat it feels that way too. Can you please answer my question. [/INST] Whether you have any associated heart, kidney, liver problem? If so, then water pills may work...but if you have infection related water in lung, then water has to be aspirated & sent for investigation to search for the cause..& doctor will start medicine for it...consult chest physician.. </s>
