Hi thanks for contacting HCM.... Noted here your main complaint is cough... Are you having habit of smoking ??? If yes then fibrotic lung disease or bronchitis or asthma has to be ruled out. Emphysema also need to be ruled out..... Do following investigation.... Respiratory examination. Chest x ray Pulmonary function test by spirometry PFT useful for differentiating restrictive and obstructive lung disease.... According to cause treatment has to be done.... You can get your sputum cytological examination as it might suggest toward diagnosis.... If wet cough is there then mucolytic drug can be taken.... Hope your concern solved. Dr.Parth
