I have been on two antibiotics for bronchitis recently.  I finished both courses and I still have pain in my lungs.  I had a chest x ray that came back clear.  I am a little worried because my mother died at at 42 from lung cancer.  The doctor prescribed two inhalers, but they dont help much.  The pain comes and goes.  I dont feel anxious or have any issues with anxiety.  I am concerned about exercising again.  Do you have any ideas of what it could be?  Maybe the infection is still lingering?
There is a large list of conditions causing chest pain. The causes may belong to any of the systems such a respiratory, cardiovascular, gastrointestinal, Musculoskeletal. There for evaluation of reason for chest pain requires detailed assessment of symptoms, a thorough examination and then relevant investigations. If someone has normal Chest x-ray picture, it's possible that infection is not so much an issue to cause recurrent chest pain.
