I was on Oxaliplatin/Xeloda and my doc’s rule was any fever that hit 100 I had to go to the Emergency Room at MD Anderson. I would hope that your docs take the persistant fever a little more seriously and I would definitely make a fuss over it, it could be very serious.
I read a story about a cancer survivor in the Livestrong book by the Lance Armstrong Foundation who had the same problem with severe hiccups that lasted for months at a time. The story said that the only thing that finally stopped the hiccups was an anti-psychotic drug and it somehow had an effect on the same thing that was triggering the hiccups. The article did mention his struggle between dealing with the nagging hiccups versus the side effects from the anti-psychotic. You might ask your doctor to research the anti-psychotics as an option? I hope this helps.
