Hi and thanks for the query, What you describe requires an intense and detailed clinical assessment. The first thing to be considered is a chronic lung infection. Pulmonary tuberculosis must be excluded. A sputum examination, chest X rays and appropriate cultures must be done. Another very possible cause is a lung abscess. A chest x ray, complete blood counts in search for elevated white blood cells counts shall be very very informative. I suggest you meet your pulmonologist for a detailed evaluation and management. I think you need medical attention for an appropriate early diagnosis, management and prevention of complications. thanks and best regards, Luchuo, MD.
