People experiencing dizziness may describe it as any of a number of sensations, such as: 
A false sense of motion or spinning (vertigo)
Lightheadedness or feeling faint
Unsteadiness or a loss of balance
A feeling of floating, wooziness or heavy-headedness
 These feelings may be triggered or worsened by walking, standing up or moving your head. Your dizziness may be accompanied by nausea or be so sudden or severe that you need to sit or lie down. The episode may last seconds or days and may recur.
