Yes, kidney involvement can be common with lupus - please do follow your doctor's guidelines regarding any diet changes that may be recommended and take your antibiotics! Often when there is kidney involvement, the doctor will specify a lower protein diet, sometimes they will ask you to lower or eliminate caffeine or other items from your diet.
My doctor tells me that the tests only tell half of it with us lupies - often my test results look best when I feel my worst, and when they look somewhat off kilter is when I'm feeling good. :roll: We're just contrary, I guess.
Try to get your rest right now, mumma7, and we're glad you re-found your password!
