Pleurisy is very common in clinical settings, with most cases caused by the invasion of Mycobacterium tuberculosis into the pleural cavity, leading to inflammatory lesions. Patients generally experience pleurisy symptoms, and if their immune function is weak, some may relapse if not careful. Therefore, for patients recovering from pleurisy, it is essential to strengthen their immune system and pay attention to balancing work and rest, avoiding spicy and irritating foods, which can greatly reduce the possibility of pleurisy recurrence. If pleurisy recurs, the clinical symptoms may worsen compared to the initial infection or may present similarly to the initial symptoms. Generally, if pleurisy recurs, there might be severe complications due to adhesions in the pleural cavity, possibly leading to persistent chest pain symptoms.
