Keep hydrated!: Dizzines can be multifactorial. Common causes of light headedness or wooziness include low blood pressure due to dehydration (sweating, blood loss) and also from hypoglycemia. If you are feeling the room spin, then it's more likely a condition called benign positional vertigo. If it persists please visit your doctor again as more thorough tests will need to be done.
