I've had sudden migraines upon waking up in the morning or that sometimes wake me up. I feel like there's nothing I can do to get comfortable and on a pain scale from 1-10 they're a 20. They are usually almost immediately relieved by vomiting. I'm not sure if anyone's seen the movie Shutter Island but the way he described his migraine is, and I'm paraphrasing, it's like someone ripped your head open and filled it with razor blades and shook it violently. I haven't seen a doctor about it yet.
