[|Human|] Hi. sometimes I feel a pressure in my chest and then I feel something moving upward towards my throat. A small white sometime hard secretion surfaces at a tiny opening in my mouth. I have strong bad breath at these times and the secretion also smells. What is it. Am i sick.
[|AI|]  Hello, In my opinion, you should consult pulmonologist and get done clinical examination, chest x-ray and PFT (Pulmonary Function Test). Chest x-ray is needed to rule out lung infection and PFT is must for the diagnosis of bronchitis. If both these are normal, then no need to worry about lung diseases. Sometimes stress and anxiety can also cause chest pressure and tightness. So, avoid stress and tension, be relaxed and quit smoking if you are an active smoker. Hope I have answered your query. Let me know if I can assist you further.
