Bodily shock

Hi, I'm 15 years old, and I've suffered from migraines for about 4/5 years now. My mom suffers from migraines and chronic fatigue. Before now I've always gotten intense, throbbing pains that often knocked me off my feet, and in researching migraines I'v found that this is in fact, common.
At about 7:30 am yesterday, I got up to go to school and felt really dizzy, like the world was spinning. This happens often, so I thought nothing of it. Some fresh air and walking dismissed it. about lunch time I started feeling really dizzy and sensitive to light, and an aura appeared in my vision. Luckily it was almost time to go home. When I got home however, I collapsed in my bedroom and stayed there all night.

This is what I'm worried about. Somewhere around 5:00 pm I started getting these "shockwaves" of pain from the back of my head down through my body, almost like electricity through a wire. Often the pain would target certain areas of my body, such as my leg, arm or chest. By occasionally my whole body would feel the pain. Has anyone else felt this or heard of this? It's the first time I can remember feeling it, and I really, really don't like it.

 I second Ann on that. Your symptoms sound like they could be something serious.

Good Luck !
