Vertigo is some inner ear thing. I'm not quite sure what sets it off for me (I think some combo of over tired and reading too much online), but basically it's like being dizzy non-stop until it passes. My Mom has it as well (I consider myself lucky, my brother got the migraines. Our youngest bro got neither. Lucky little shiite.)
3 years ago I had it so bad that I literally couldn't stand up. Got out of bed and fell over/down. Laid in bed for three days and just slept/listened to TV with my eyes closed. Anytime I opened my eyes it was like the vertical hold (remember that on TVs?) was off in my life, except the vertical hold was horizontal for me -- if that makes sense.
Still feeling physically a little off-kilter, but much, much better.
