So, thru the years I've had migraines - always the same triggers & location in my head. Last week had my first Complex migraine. Although I have no pre-cursers for stroke, I too questioned if I was having one.  Speech slurred, walked like I was drunk, and left arm numb/tingly, neck pain with a head shattering migraine unlike ANYTHING I've ever had before, and not in the location that I get migraines. Also, none of my triggers were present PLUS it came on fast outta no where 0 I usually "build up" to a migraine. I went to bed & woke up with it still (thats a new one). I Went to the Er, and they gave me a shot, and 4 pills (Benadryl, Compazine, and Toradol).  I questioned the benadryl?? Apparently, the anti-histamine will relax your blood vessels (alleviate migraine... NOW they tell me?!) the other stuff was an anti-inflamatory and I can't recall the other one. Online says its for nausea, etc., but thats not why they gave it to me. So who knows. All I know, is within 40min I felt normal again and w/out pain.  I informed the ER staff and they said they'd test me before releasing me.  Basically 'stroke patient tests'.  I'm 39, and failed the last test.  Put your arms straight out in front of you, palms up & close your eyes while they count to 10.  Apparently, my left arm "drifted" down - they tested me 2x. Failed both. Off to catscan, which they said - unless you had a major stroke will show nothing. You need an MRI, to see mini-strokes and migraine effects. (No idea why they didnt give me the MRI). Anyhow, I've been referred to neurologist - to see where we go from here.  This was the first time I've ever heard of a complex migraine and yeah, its a dangerous one. They told me if I start having another to go IMMEDIATELY to the hospital. This aint a normal migraine people.  *Migraines do run in my family - family members who had gallbladders removed (other reasons) noticed that afterward, they never had a another migraine??? Related??)  Good luck everyone.
