Even Nick Cannon does not know exactly what is wrong with him. He says that he has an autoimmune disease like Lupus, but it is not Lupus. So what is it? He never says. He just says that he will continue to suffer health issues for the rest of his life. I noticed that none of these issues started until after he got together with Mariah Carey. Stress? Body breaking down? Nick almost died a few months ago when blood clots floated to his lungs. He also has kidney disease and the proud father of dem babies, and the worst baby names of all time.
