There's this migraine that is preceded by a visual aura, and this visual aura, by the way -- and I'll show you a picture -- but it sort of begins with little dancing lights, gets bigger and bigger until it fills your whole visual field.
这就是有预兆的偏头痛 对于这可视的预兆，我会给你们看一张图片- 开始显示的是一些小小闪烁的光 然后慢慢的变得越来越大，直到它填充你的整个视野。
