I used to get the aura, with no significant pain... I say, 'used',
hoping that I get no more! Started in my 20's, but has decreased in
frequency (never very frequent) over the last 2 decades... never been
formally diagnosed but have come to realise that's what I get,
migraine without the headache, or if I do hurt, very low dull pain.
Lack of enough sleep, AND lots of stress, seem to be the most common
trigger, although I have on occasion been taken quite by surprise when
they first began in my youth. Now, I can sometimes kinda feel when
I'm at risk for getting one... just the way my vision behaves warns me
to calm down and chill out. For good measure, I'll grab a Coke and a
pack of Reese Cups.
If it happens, I pop 2-4 Ibuprofens, grab a coke and any chocolate/
peanut butter I can lay my hands on, and if I can, lie in a dark room
and try to relax and chill for the next hour, preferably the rest of
the day if I can. I have noticed that when I'd freak and get even
more stressed, and not do anything to alleviate them, I have on at
least one occasion had the thing start all over again as the
fortification lines were about to slide off the edges of my vision.
Since I learned to just stop what I'm doing for at least a few
minutes, and chill, that hasn't happened again. Indeed, now that I
know what triggers them for me, and how to ward it off (avoiding
getting too stressed, Coke and Reese's), it's very rare that I get one
anymore.
