Lung nodules generally do not cause fever, but if the lung nodules are caused by an infection, they may lead to fever.

A lung nodule is an imaging finding, often discovered during physical examinations or other disease screenings. There are numerous causes of lung nodules, which may be due to conditions such as lung infections, tuberculosis, benign lung tumors, or lung cancer.

If a pulmonary nodule is caused by an infection, the patient may experience symptoms of fever, but the severity of the fever is related to the severity of the infection. If the infection is relatively mild, the patient may only have a slight fever, whereas if the infection is more severe, the patient may experience persistent high fever.

It is important to note that not all pulmonary nodules cause fever, nor is all fever caused by pulmonary nodules. If fever occurs, it is advisable to seek medical attention promptly to clarify the cause and follow the doctor's instructions for standardized treatment.
