Me, again. And thanks to both of you for your responses. I do have a highly qualified oncologist/hematologist at the large teaching hospital here, whose staff I see every four to six months or so; they're the ones monitoring my need for Ivig infusions. She has said that since my disease was discovered at a very early stage, it does not warrant treatment and that things might stay this way for quite a long time. I've been told what to watch for (night sweats, pronounced fatigue, etc). But I'm still curious about what others have experienced, particularly those who've gone for years without actively treating the disease. Does it flare up? Is there pain? Is my current, mild head cold a harbinger of things to come? The answer may well be "It depends!" But I'm trying to get a handle on how worried I should be. How big a deal is this?
