[|Human|] for a few days now, I have some mucus in my throat but no soreness. My chest feels a little heavy but my breathing is not satisfying but its not labored. Its feels worse when I am out in the cold weather. I am also a smoker but not a heavy smoker, about 5 cigarettes a day.
[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. Smokers are at increased risk of lung Infection and bronchitis. And both these conditions can cause similar symptoms like mucus, chest heaviness and difficulty in breathing. So better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. Chest x-ray to rule out lung infection. 3. PUT (Pulmonary Function Test) to rule out bronchitis. You need to quit smoking as soon as possible. You may need antibiotics, inhaled bronchodilators and inhaled corticosteroid (ICS). So better to first diagnose yourself and then start appropriate treatment. Hope I have solved your query. Wish you good health. Thanks.
