My father had some water getting blocked in the path between lungs and
liver 3 years back and the doctor consulted him to take 3years of medicine but after he was completely cured he stopped taking medicines after 3 months and now exactly after three years he encountered the same problem i.e.water getting contained in that particular area and the doctor has told him to take the same medicines for more 3 years andhe told there's absolutely no problem.Is there any connection of that with coughs??
