Diagnosed with CVID (Common Variable Immune Deficiency) 18 months ago. Treated with gamma globulin intramuscular infusions to which I was allergic and which caused a week's long hospitalization due to Serum Sickness (basically, my blood was poisoned by the infusions). I am still not well (major fatigue, frequent infections, etc.) and don't know from whom to seek help. The only doctor in my locale (Santa Barbara, California) who treats CVID is the one who ordered the infusions but didn't bother to monitor what was happening to my blood, so I can not trust him.
There's a concurrent problem that may be related to CVID: very copious anal mucous discharge for which neither GI specialist I've seen has offered a solution or satisfactory explanation.
