I actually went to the ER a few weeks ago because I was afraid of hurting myself more than for the pain of the attack, even though that was one of the reasons too. I also had some twisted ideas like cutting myself/overdosing on meds so that they would have take me more seriously at the ER if I did. One odd version of "self- to get attention". Because the first time I went there the only thing they did was making sure I didn't have meningitis and a indomethacin+antiemetic IV, no neurological or vascular assesment.
The other time they just asked questions, they didn't even take my blood-pressure. They were busy with a few red codes, so I understood I had to wait 4 or 5 hours minumum. It's not like I'm dying. But maybe since I barely can stand and the chairs are all metallic, the lights super-bright etc...and you KNOW a migraineur (migraineuse?) needs quiet, dark and rest, you can give me a pillow or a weelchair with brakes working and that can recline. After a while the pain got better on his own, though I felt much more tired and I went back home with no treatement at all. Either it would get better, so now ER, or worse and my code would go from green to yellow.
So now I know that if I ever needed to go to the ER I will have to take me a pillow or, even better, pretend I'm worse than I am and call the ambulance so I can lie down on a strecher. I hate faking it, but they force you to.
