my friend's mom had one and it was more painful than giving birth

hi im 18 years old and last night i had a bad headache or migraine near my right side of my eye or eyebrow all i know is it hrut alot and the next day it kinda went away but i feel really dizzy and my head feels weird im really worried now any suggestions?

I'm 18 and 4 the last 2weeks ive had a headache and at times it sonds like popin noises in my head and pain around my left temple and eye is this a sign because i had a head cat scan and nothing showed up but im still worried?

These were my symptoms (mine actually ruptured at age 12) the night before I had a VERY bad headache, I had a history of these since I can remember I was dizzy, vomiting, weak, fainted, after I heard/felt a "popping" in my head I fainted again, and in the ambulance I was throwing up blood from what my mother tells me.
