It's been few months and coughing in night and morning is there. Sometime in morning when waking up also feels shortness of breath. From last 8-9 months body has slimmed down a lot. I though this is normal with the age but this cough and all has put me to think that I should do something about it. I consulted a doctor as well but his medicine is not of much help. Can you advise me which type of doctor shall i consult or maybe any specific doctor whom I can consult.
