I've Been Having Migraines For About 8 Months. For The

I've been having migraines for about 8 months. For the past two weeks they have become a lot worse. They last for days at a time and when they are at their worst I can barely walk from being so dizzy, I vomit constantly, and my vision goes in and out of focus. Is there anything I should worry about or is it just part of having migraines.
