Hello ! I can understand your concern. Considering your history you seem to have pleural effusion (fluid collection around the lungs) due to cardiac problem likely heart failure.  As your heart has got weakened, it might be unable to pump blood normally and because of this there is seepage of fluid in the space around the lungs. To confirm this you should go for an echocardiography which gives a clear idea regarding the functioning of your heart.  One more thing to be done is to send the fluid aspirated from around your lungs for analyzed.  Complete analysis report of the pleural fluid will point towards the most likely cause for the fluid collection.  The most important treatment for pleural effusion due to cardiac problem is to treat the underlying cardiac problem adequately. Once that is done, eventually the fluid will also reduce - most likely you will need T. Las ix which flushes off the exceed fluid through urine. Also Consume less than 1 liter water per day and restrict salt intake, these help in reducing the fluid collection. So the next thing you need to do now is to review with your cardiologist and also consult a pulmonologist to have your fluid aspirated and analyzed.  Hope this helps.  Do Chat Doctor.
