Lupus can attack almost any internal organ. In my case it got my kidneys, joints, and my entire GI tract.
The immune system can "attack" almost any part of your body. Lungs, heart, blood, kidneys, nervous system and more. Do a google search and you will find out lots of information about it. Some lupers have terrible problems and others have none. Just don't ignore any new symptoms even if you don't think they have anything to do with lupus. They just might.
