Hi. I understand your concerns. Even occasional smoking is harmful. So quit smoking before it causes more harm to you. You will also need to undergo a chest x ray to look for infection. Consult a pulmonologist for the same. Hope your questions were answered. Thanks

Hello , pain in tracheal region is called throat pain . chest pain is pain in the area on both sides of sternum . You better quit smoking because habbit starts with one cigarett and gradually increases . You cannot quit when you completely get addicted to it. But one cigarettes will not cause chest pain . you might be having some other problem ,consult general physician.
