Make sure you are treated for hypertension (if you have it), and get your blood work done as requested by your rheumatologist (or primary or nephrologist) as that's the only was they can track it's progress, unless you have a more severe condition that caused your kidney disease.
Also, be sure to tell your health care provider about all of the over-the-counter medications you take as some common ones such as Tylenol can adversely affect your kidneys.
