Markus-We'll see tomorrow. He just had the 1st injection on monday. Did you have these symptoms? I think the nurse is more "on the ball" than the doctor. The doctor that was on call this morning didn't think the meds caused the problem but it says right on the sheet that these are possible side effects. He has already been weakened by chemo and radiation that ended in December. I don't know why it would be improbable that this is a reaction to the Erbitux.
