when i stick my chest out and take a deep breath sometimes i will feel a pop or a click, not sure if its my chest or lungs. im sure its my lungs. i smoke and have asthma.. what could this be, there is no pain. a few times i have had chronic bronchitis. when i dont smoke as much it seems to gradually click pop crack less noticeably.. i wonder if i quit long enough it will go away. please help. thank you.
same spot most of the time upper right quadrant.
