How long it usually takes for pleurisy to heal is related to the type of pleurisy, treatment, etc. and needs to be analyzed on a case-by-case basis. For pleurisy caused by bacterial infection, it can usually be cured in 1-2 weeks after medication. If pleural inflammation is combined with pleural effusion, drug treatment alone is less effective and requires drainage of the pleural effusion, which can reduce the infection and improve clinical symptoms. In the case of pleurisy caused by tuberculosis infection, also known as tuberculous pleurisy, the treatment period is often about 1 year. Therefore, in case of inflammatory pleural lesions, patients are advised to go to the respiratory department or thoracic surgery department of the hospital for differential diagnosis, and then follow the analysis and opinion of a professional doctor for standardized and individualized treatment after the etiology is clarified.
