I get migraines with aura. They're horrible and I wouldn't wish them on my worst enemy.
I had my first one when I was 13. I'm now 23, and I still get them. Mine happen like this:
-First I get a little "blob" in my vision. I don't know how else to describe it except as a void - I can't see anything in that blob, which can be anything from the size of a 5p coin to the size of a tazo (anyone remember those?)
-While this happens, I get a cold sweat all over my body, and a feeling of panic sets in.
-The blob slowly gets replaced by a small backwards "C" shape, which flashes in all the different colours of the rainbow.
-This backwards C slowly increases in size (this takes around 20-30 minutes).
-Once the C disappears, I get a killer headache. It feels like somebody is trying to cut my head open with a blunt axe. I still have the cold sweats, and I also feel nauseous.
The only way for me to recover from this is to sleep. I usually need 3-4 hours asleep before I can wake up and function, although I still have the headache. I usually have the "migraine hangover" for about 48 hours after the migraine - if I turn my head too sharply, or look out of the corner of my eyes instead of turning my head fully, I feel a dull stab of pain in my head which I can only describe as being the ghost of the migraine. Lately, I've been getting migraines in my sleep - I see the aura in my dream, and then wake up with the pain.
We can't seem to pinpoint a trigger, although caffeine and salt seem to do it. I stay well away from caffeine (and in fact describe myself as being intolerant to caffeine) and I do my best to avoid salt. I do suspect that hormones may have something to do with it too, so I've been keeping a period/migraine chart to see if I can spot a pattern.
I am terrified of getting migraines. In fact, if I see anything whilst out and about that resembles a backwards-C shape, I find myself getting the cold sweats and feeling of panic in the pit of my stomach, purely because it reminds me of my migraines.
