Head will start hurting then left eye start hurting entire face hurts then she passes out ?

That sounds scary: If not a known, treated issue, then the ER can evaluate. Most people get a headache at some time, such as from colds, infections, lack of sleep, too much driving, long hours on the computer, stress at work, etc... A bad or increasing headache, recurrent headache, weird headache, or with other worrisome symptoms like this case must be evaluated.
