Nonspecific: More information about your symptoms is needed in order to advise you as your symptoms are nondiagnostic. A physician will take a thorough history and perform a physical examination, and then order appropriate tests in order to make a diagnosis. In the meantime follow a bland low fat diet and see your physician if symptoms persist..
