Was it a seizure or did I pass out?

I don't know how to tell if last night I either had a seizure or I just passed out. I do know that this has never happened to me before.

I was getting up from a chair and as I got up, I got extremely dizzy and my vision was unfocused. I was holding something in both hands (a lighter and a drink).

As I felt myself get dizzy, I sat back on the chair. My boyfriend was home with me and all of a sudden he goes "what's the matter? what's the matter?" Well, my eyes were rolling in the back of my head, I dropped whatever I was holding and, my head and neck (as he puts it) were jerking back and forth. I was aware he was asking me what was happening, but all I could say was "what" over and over again.

As I started to come out of it, I remember everything from it. I remember shaking my head, and my eyes going crazy, and I heard my bf talk to me.

It has happened in the past that I get light headed when I stand up to quick (i have anemia) but this has never happened. I usually feel better within seconds. I also use to pass out when I was younger from the anemia, and it had never happened like this.

Also, I guess I should mention that in 2007 I was diagnosed with Pseudotumor cerebri (Idiopathic intracranial hypertension), but I guess you can say it has been sort of "dormant" for almost 2 yrs, I haven't been on any meds for it in 2 yrs, and I haven't had major headaches related to it.

So...did I pass out or did I have a seizure? Should I call my neurologist or just my PCP?
