Pleurisy is common in lupus and is most often treated with corticosteroids (such as Prednisone). You are absolutely correct that stress can make the symptoms worse and can make them last longer. You should not be in such pain for such a long period of time, an excess amount of fluid can accumulate in the pleural space. This is called a pleural effusion and occurs less often than pleurisy and is a more serious condition than pleurisy. I would suggest that you contact your doctor to start treatment before your condition evolves into something more serious.
