Hi Joy,
I am so sorry that you are not feeling well. It's interesting reading what you wrote because years ago (before I was even diagnosed), they had run an IGG on me and found that it was low, but no one ever said it was a big deal. At that time I had fatigue that was debilitating and kept getting infections. I also had bouts of bronchitis and eventually, pneumonia. I wonder if other Lupus patients have ever experienced this. I am sending you a warm, gentle hug, Joy. Take care and do feel better.
Love,
Laura
