hi barbara,
ive too got a vp shunt, mine malfunctioned 3 weeks ago and i have it replaced immediately.

i was sick all night, constatly i was unable to keep down medicine and liquids and had a blinding headache. also it was very had to wake up and open my eyes. these are all signs of a malfunctioning shunt...i was lucky enough to have been in hospital that night, otheriwse i probably would have been dismissed as having a migraine.

i had my shunt revision in the morning and i was out the next day, as a typical revision patient is out 24 hours after surgery =]

im sorry to hear about your daughter and hope this is sorted out sooner than later, best of luck to her, you and your fmaily. take care x
