My 14 year old daughter developed hydrocephalus in November and had a VP shunt placed. they have no idea what caused theproblem. She just bega having nausea ad headaches. Sh s doing well with a few problems and wondering about them. Sometimes when she wakes up she is nauseaus and throws up.... anyone have this? Afterward she feels fine. She feels hungry ALOT and feels like she needs to eat slowly. Thanks
