I am not actually receiving treatment yet. I was diagnosed with CVID about 3 weeks ago by an immunologist. I also have Hashimoto's. I have a lot of stomach problems and pustular psoriasis, so my dr. tested me for Celiac. It was negative but he noticed my Vitamin D and IgG was low. He ran more tests and found my IgA was low too. I have built up antibodies to about half of the pneumonia vaccine strains and have responded very well to tetanus vaccine. However, he explained that I may have had the vaccine before CVID. He is concerned insurance wouldn't cover IVIG. He suggested I come back in 6 months to be retested and see where my immunoglobulin levels are before starting treatment. I think he is trying to build a case for insurance coverage. Is IVIG inevitable or is it possible to avoid treatment? I have been more sick in the last 4 years than I have my entire life. Although, I generally try to tough it out because my doctor is hesitant to write scripts, plus I feel like a hypochondriac sometimes. Is it better to have treatment even if the symptoms are not severe? I would say my symptoms are not life threatening but I wonder if I would feel better and have less illness. I would like to hear about others experiences.
