What are the symptoms of pulmonary tuberculosis?

Pulmonary tuberculosis primarily affects the lungs and often develops gradually. Common symptoms include a persistent cough lasting several weeks, sometimes producing sputum or blood, along with chest pain and shortness of breath. Fever, night sweats, fatigue, loss of appetite, and unintended weight loss may also occur. Symptoms can vary in severity, and in early stages they may be mild or nonspecific.
