I just got back from my pain doctor, he said I have water in the lung.and for me to continue to take deep breaths even though it hurts terribly. Because he.  Doesnt want metro get a collapse lung. I have copd bad. And both lungs have hardening.what causes water in the lungs and a collapse  lung?
Hello, Water in the lungs is known as pleural effusion. It is known to cause the collapse of the lung. So your collapsed lung is due to pleural effusion only. Common causes for pleural effusion in COPD patients are 1. Right-sided heart failure and cor pulmonale 2. Lung infection like tuberculosis or pneumonia3. Pulmonary embolism. So better to consult pulmonologist and get done 2D echo, fluid examination, and CT pulmonary angiography to find out the cause for pleural effusion. Hope I have answered your query. Let me know if I can assist you further.
