I just posted this in the other thread, but I'm sure not everyone is going to look in both. For me, the only precursor I have for sure before a migraine is yawning. If I begin to yawn every few seconds, I know a migraine is going to hit me. Sorry, let me rephrase that. I always have a migraine, just the pain level differs. If I begin to yawn that much, I know the pain level is going to skyrocket. It doesn't happen all of the time, just sometimes.
Every once in a while, the nausea will hit me hard before the migraine pain gets worse. Those are the only two things that let me know the migraine will be bad. Majority of the time, it just hits with no warning at all.

Mine are usually visual, black spots, thing that aren't there that I see in the corner of my eyes, having problems reading or recognizing faces etc. They usually start 10-15 minutes before my migraine hits. It comes in a package with allodynia, which usually starts two or three minutes before the migraine.

I usually feel unwell in general, like something is not right. I become very sensitive to temperature and I either feel too hot or too cold all of a sudden. I have sensitivity to light and sometimes sound. I feel nauseous. Usually I get my aura in that sequence.

I also occasionally get visual auras and see spots of light. Recently, I had vision loss for a few minutes as an aura. If I'm reading, I get blurred vision. I can also get numbness in my arms.

Knowing your triggers and aura symptoms can really help reduce the amount of pain you feel during a migraine. I hope you find out what they are so you can have less severe migraines.

I get cold/the chills. Sensitive to loud sounds, and bright lights. I feel nauseous, and off balance.

Thanks for sharing, all!

I feel off...kind of out of it....and people start to sound far away and then lights hurt my eyes and I get light headed and sweaty and THEN I have visual disturbances light lightening flashes. About 45 minutes to an hour later I get a bad headache.

I get what seems like an after image, as if I'd looked at a light. Then it grows and develops rainbow colours - looking a bit like a multicoloured crack in glass. It usually also moves - sometimes to the centre in which case I usually have to give up doing anything even reading.

then the headache arrives. For me they are not too intense but it doesn't go quickly or with pain killers.

I have a migraine every day, but when it starts to ramp up, I get what I call "sparklies", which is like a meteor shower, across my line of vision in my left eye. Then I know I'm in trouble. Loud noises and bright lights drive me crazy. I carry foam earplugs with me at all times.

One time I was working on my computer and my line of vision got more and more narrow, and turned into kind of a kaleidoscope or prism. It was so weird, and only lasted a few minutes. I called the advice nurse and she said it was another form of an aura. It's never happened since like that.
