I have a 12 year old that has been suffering from migraines since he was 5. He gets a headache, and starts vomiting and most of the time it completely knocks him out for the day, but when he wakes up it's all better. It might be possible that your daughter is getting headaches at the base of her skull and the best way she can describe it is neck pain. My son takes meds at the onset of the pain and sometimes it will stop the progression of pain to vomiting but most times he goes thru the whole process. Just a thought.....but a ct will help to diagnose if it is migraines.....
