Vertigo is the sensation of movement ( room spinning ) when no movement is actually occurring. Dizziness needs to be distinguish between vertigo, presyncope (people feels like they are going to black out; vision and hearing may become obscured), disequilibrium (off balance), and light-headedness (no rotational component, no movement). There are many different diseases and many different medications that can cause veritgo. Unfortunately, this is a symptom that is going to need further work up from your primary care physician. 90% of the time it is a condition called benign paroxysmal positional vertigo. It is essentially a dysfunction of the inner ear. Occasionally, people will also get ear or sinus fullness. I would recommend seeing your primary care doctor very soon. In the meantime: -go to a local grocery store and have your blood pressure checked -Limit salt intake -try not to make sudden head movements -if you develop weakness, numbness, tingling, vision changes, speak difficulties, facial droop, or stroke symptoms, you need to go to the emergency room immediately. -caffeine and alcohol can worsen vertigo
