Warning Signs Of Pleural Effusion

Dry Or Productive Cough

A productive cough produces phlegm, while a dry cough occurs without producing fluid, and when related to pleural effusion, the cough tends to be chronic. Any cough that lasts for more than three weeks should be evaluated by a medical professional, as it may be a sign of a more serious underlying medical condition. Some patients may experience a cough without any other associated symptoms.

The most common cause of pleural effusion is lung cancer, which is often the underlying cause of the coughing. Patients may cough up bloody sputum. When a cough produces blood, it should be evaluated by a medical professional as soon as possible, even if it hasn't lasted for three weeks.
