Re: What could be the cause of reoccuring colds?
Viral infection is probably the most common cause of pleurisy. Other diseases that can cause pleurisy are lung infections, such as pneumonia and tuberculosis, and other diseases such as systemic lupus erythematosus (lupus), rheumatoid arthritis, cancer, liver and kidney disease, heart failure and pulmonary embolism. Other causes include chest injuries and drug reactions. Pleurisy can come about from unkown cause.
Once the underlying disease is cleared the pleurisy should clear also. No, I do not believe pleurisy is your problem now but you may be suseptible to pleurisy in the future.
No doubt your immune system is not up to par and you are being exposed off and on to viruses or bacterial infections. Viruses usually run their course but may need meds for secondary bacterial infection. Many viruses are rampant at this time.
