Common symptoms of pleurisy include chest pain, which often worsens with deep breathing. This condition is also called pleuritic chest pain. It is important to note that the presence of such chest pain does not necessarily indicate pleurisy; it could also be due to pneumonia, pulmonary embolism, or even rib fractures. Patients with pleurisy may also experience a sensation of chest tightness, especially when there is a significant amount of pleural effusion. Furthermore, severe chest pain caused by pleurisy may lead to patients avoiding deep breaths, which can also result in symptoms of chest tightness. Fever is another common symptom in patients with pleurisy, and the severity of fever can vary depending on the infection causing the pleurisy. For example, tuberculous pleurisy, caused by tuberculosis infection, often results in a low-grade fever in the afternoon, but high fevers can also occur. In the case of purulent pleurisy, which is usually due to a bacterial infection leading to pus formation in the pleural cavity, high fevers are common.
