Clearly i'm not there to examine her , as would be the best option, but from what you have told me I'm not too worried.
If however she devlops a headcahe, becomes drowsy , confused or vomits you would need to get her to a hospital ASAP.
As mentioned - gettng her checked out at the moment is the most appropriate course of action.
