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 wouldn't stop the sub q. I do get some locals swelling and redness. It seems to increase a bit as infusion continues, then decreases. After infusing I do have some redness around where I infused. I goes away in a day or two. I use a heat pack on abdomen while infusing because it feels good. It is a heat pad that is filled with buckwheat seed and it's a bit heavy but he pressure feels good on my abdomen. Th next day I have some swelling and tenderness and I switch to ice.
If trying a different allergy Med doesn't work can you decrease your dose of Benadryl? You could always by the children's liquid and take that smaller dose.
