Well - it turned out to be a shunt malfunction. She woke last Saturday with headache and throwing up. The ER did a CT which showed O.K. The neurologist decided to do a lumbar puncture to test the pressure and it was slightly hig, but the CF fluid was cloudy and protein levels high. They went in and found the end attached to the venticles was clogged due to the high protein. They replaced it. The only problems she is having is 500 mg protein in CSF when it should be 45 and some low T cells. Tommorrow she is having a gallium test. But, it looks like the intermitant headaches and nausea were caused by the shunt.
