Lung nodules: These are always abnormal but can have many different causes, including infectious and non-infectious inflammatory conditions (i.e., sarcoidosis, etc.), drug reactions, cancers, etc. These need to be carefully evaluated by either a pulmonologist, thoracic surgeon or other expert familiar with these conditions.

Yes: Even outright pneumonia can look like separate lung nodules if they are patchy. Inspissated mucous plugging certain airways can also look like nodules and the inflammation can cause pleuritic pain. Treat the current condition with antibiotics if needed and expectorants to make coughing easier and if needed steroid to decrease inflammation.
