The local symptoms of tuberculosis primarily require us to understand where tuberculosis occurs. Currently, tuberculosis in the lung tissues, trachea, bronchi, and pleura are all classified as pulmonary tuberculosis. The primary local symptoms are still respiratory symptoms, with the most common being cough and expectoration. Patients with tuberculosis generally have a slow onset, with most experiencing cough and expectoration that can persist for two weeks or more. Some patients may also exhibit symptoms like blood in the sputum or hemoptysis. Additionally, some patients may experience other symptoms; for example, those with pleural involvement might have irritative cough, chest pain, and difficulty breathing, while those with tracheobronchial involvement might exhibit a prolonged irritative cough. Some patients may also develop bronchial stenosis, which can lead to difficulty breathing.
