Hello! My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.
Can you please elaborate what are your concerns and what serious thing or condition you are thinking of?
Lung cancer is associated with smoking if you smoke for almost a decade . It does not appear that early with smoking. Your symptoms are likely to go away with your treatment. If the pain is not getting better with paracetamol you can take some anti inflammatory like Advil to get a relief from pain. Just relax I reassure you it is not a lung cancer or anything serious. If your symptoms persists after a week then you can have a chest X-Ray and a course of antibiotic to help get rid of the infection.
Feel free to ask if any more question
