You describe “lung
pain on both lower lungs for 4 months.”
The lung itself, when diseased, does not cause
pain. The membrane that surrounds it, the pleura, can cause pain when inflamed for any reason, infectious or other. This is called pleurisy and is a pain that is characteristically worse with breathing. When the pleura is irritated/inflamed sooner or later it is associated with an abnormal collection of fluid within the chest, called pleural effusion.
