What do you advise if i have chronic cough i can understand but "isolated"?

? any medical checks: Your doctor can check and examine you and guide you further. Tell us if you have had much in the way of medical checks or not? Typically cough is caused by either infection(bronchitis) from virus, bacteria or fungus) and a chest X-ray is a simple test to check for it. If there is no infection found, cough can be due to allergy(airway sensitivity) or low grade Asthma.
