So vertigo, this perception of falling or dizziness, needs to be distinguished from lightheadedness. So if you're ever feeling dizzy, it's worth stopping and sitting, or if you can't sit, standing and closing your eyes and asking yourself a question. Do I feel like I'm ready to fall straight down, or do I feel like I'm going to spin and fall down? Because in answering that question, you can determine whether or not you are lightheaded, that would be the straight falling down, or you have vertigo, which is you're dizzy, which is that you're going to spin and fall down.
