My mother is suffering from cough from past 15 days. This occurs more when there is smoke, when some scent smell occurs, but during night at around 3:00 it starts.. It is not continuous cough, but she will be coughing.. She even tried salt water gargling, steaming, etc., but no use. We can't even go to a doctor because of the situation. I can't even judge whether it is wet cough, dry cough, allergic cough. It would be really great if someone help me in this matter. She takes Montek LC... Please help
