My 5 yr old daughter has a headache. She woke up and threw up, is dizzy and has a low grade fever. Any ideas? Please help.

Fever. her symptoms suggest an infection. Treat her fever/headache with Tylenol (acetaminophen) and give small amounts of fluids, such as Pedialyte. If she is not improving have her checked. All the best and I hope she feels better soon.
