Many: Irritation of the lungs or throat are very common. This can happen with a simple cold (respiratory infection.) of course smoking is a frequent irritant. Coughing itself can irritate the respiratory tract. A foreign body can be inhaled and do it. Pneumonia, congestive heart failure, cancer also. If there is blood see a doctor. If you are worried, see a doctor.
