Touch wood I have not had a migraine in at least 5 years. However, when I used to get them, they would always follow the same pattern. To begin with, my eyesight would deteriorate to almost non existence. This would usually last about 45 minutes. Suddenly it would come back to perfect, and at the exact same time I would get the most exquisitely horrific headache. I would also feel some tingling in my arms and legs (thankfully nothing like my mother's symptoms, one side of her body would go entirely numb during a migraine). The only cure I found was to go and lie down, and sleep it off for a couple of hours.
