Update on Dave's condition: We still don't know what's going on, but whatever it is, it ain't good. His condition has deteriorated rapidly in the last three weeks and he spends about 22 out of every 24 hours in bed. He's in pain, he can't sleep, he can't eat much, and if he tries to do anything besides rest in bed, his lips turn blue and he starts gasping.
We saw the oncologist today and he ordered a boatload of more tests. The working hypothesis today is that he has hemolytic anemia as well as some kind of systemic infection. But that's still a guess, at this point. None of the labs that were done so far present a clear-cut picture (hence- more tests.) They took enough blood today to make a healthy person faint.
He started on antibiotics (Levofloxacin) today. Tomorrow we go to radiology and Friday we see the doc again. The doctor is also trying to set up a Gamma Globulin Infusion for Friday, if the insurance will cover it.
