Welcome to our family. I have not had any renal complications with my Lupus, so I am unable to help you in that area. I know that some of our members have dealt with this and, hopefully, will respond to your post. I just wanted to make sure that I welcomed you and to let you know that you are definitely not alone! Although many of us may not share your exact symptoms, we are here to help you as much as we can.
I wish you the very best!
Peace and Blessings
Look For The Good and Praise It!
