Common Variable Immunodeficiency Support Group
Common variable immunodeficiency (CVID) is a group of 20-30 primary immunodeficiencies (PIDs) which have a common set of symptoms but with different underlying causes. CVID's underlying causes are different, but the result of these are that the body doesn't produce sufficient antibodies in response to exposure to pathogens.
I'm sorry to hear you are sick, I hope you start to feel better. I don't know anything concerning the thyroid cancer thing but I hope it's just an infection they can treat real quickly. I have had my thyroid become infected and it is painful as well as a pain in the butt.
Good Luck keep us posted.
