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.
BTW, I take Norco as well and it has Tylenol in it (dosage on mine are 10/325 - 10 being the amount of pain med and 325 mgs of Tylenol) so I don't add ADDITIONAL Tylenol on top of it either. You should be fine just let the nurses no why you are declining the additional Tylenol. Keep ups updated! It will be gradual but you will feel better, not perfect and far from normal but it can be manageable!
I will be so happy to start feeling better! Manageable & functional would be a big step up for me. I think normal is over-rated ... what's normal for me is to be sick all the time, so I would be happy to step away from "normal" :-)
