Seek advice: You won't know, necessarily. Vertigo is a sensation of spinning or motion of the person or the environment, while dizziness is not a sense of motion but lightheadedness or feeling floaty or off kilter. There can be neurologic issues, inner ear problems , visual problems, psychologic issues, cardiovascular problems, and many other causes. See an ENT, neurologist, and possibly cardiolologist.
