Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Has your daughter been in contact with anyone else who is ill? In an otherwise healthy child, what you describe headache,
vomiting and
abdominal pain is most likely due to a viral infection. There are many viruses circulating in the community now and it is probable that she caught one of them. If this is correct, she ought to be better in a few days.
As for treatment, it is important that she is not given
Aspirin. She may have
acetaminophen or
ibuprofen for headache. At this point, don't worry about her intake of solids, but concentrate on liquids. Offer her something to drink every 2-3 hours. When she is better and gets hungry, she will request something to eat.
I hope she recovers soon. Please return if we can be of further help.
Regards
Dr. Arnold Zedd, MD, FAAP
