Migraine headaches/ Is this a migraine, Can they start without a person having any prior history of them?

(My Original Blog Post: http://www.latesttrendsguide.com/?p=2663)

What I mean to ask is this likely a migraine? I have never had a headach EVER (other than just mild sinus ones when I was sick a few times years ago). Then about a week and a half ago I got one and it never completely went away, some days are worse than others. It started out with a dull, ache which seemed to be behind both eyes or around both eyes, and a feeling of nausea that seems syncopated with the eye pain. When I get a surge of eye pain, the qweezy feeling gets worse at the same time. eventually I got pain on the very top of my head and the Back of my head too. I almost vomited the first day it started, I got a really dry mouth and Hot flashes. That ended after about a day and now my head just hurts in different places at different times of the day.
Anyway, my longwinded question can be boiled down to this. Does a person who never had migraines in the past, just all of a sudden get a migraine like that and have it last so long without any prior history ?
I forgot to mention, within an hour of the headache originally starting, I did two things that I can recall that may have had something to do with it. First bent down and attempted to push my bed mattress really hard to move it sideways ( I was moving my bed) then the second which was within a hour of the pain starting, was I just Shaved. When I shave I bend my neck upward for awhile while so i can see my neck as I shave. I didnt notice any pain during any of these acts, but those were the only two activities that I can remember having done shortly before the pain started.
