I have an appointment with an immunologist but it's not for about three more months because that's how backed up there. I just think it's strange because I really don't get sick very much and I haven't had any infections or anything until all this just happened suddenly. They found out I had Mac and small bowel cancer, within 6 weeks, well originally they thought the Mac was lung cancer also and they still thought it was cancer after I was diagnosed with the MAC, and I believe they thought that all the way up to the last CT scan where everything shrunk and looked better. I hope they figure out the underlying cause of all this!! It's nerve-wracking because I feel something's wrong with me but they don't know what it is.
