The inner ear serves two purposes: hearing and balance. There are mechanisms in the ear that inform the brain about your position, orientation in space and movement and all times to keep you in balance. A false sensation of spinning or whirling, known as vertigo, can occur when the signal to the brain is blocked or misfires. In addition to the sensation of dizziness, symptoms may include headache, nausea, sensitivity to bright light, blurred vision, ringing in the ears, ear pain, facial numbness, eye pain, motion sickness, confused thinking, fainting and clumsiness.
Dizziness can also be a symptom of a more serious medical problem, such as high or low blood pressure, heart problems, stroke, tumor, medication side effect or metabolic disorders. Therefore you should always seek medical attention if you experience ongoing or repetitive dizziness.
