I also have an immune deficiency currently labeled CVID but more likely Hyper IgM. Getting right tests is hard. Recommend anyone with Immune deficiency contact Immune Deficiency Foundation (IDF). Lots of excellent, free information, conventions. For second opinion in North Florida, try Dr. S. Joshi. My total IgG just dropped low enough for insurance coverage. Hoping treatment will reduce frequency and severity of infections. Have 2 types of arthritis and two types of cancer. Not giving up.
