The last 4 days I have felt very dizzy and I also have a headache ( in the lower part of the head) and have nausea. Experiment mild dizziness even when I'm sitting . If passing a lying position to a standing always makes me dizzy and almost fell .

Vertigo - the - spinning sensation may be due to many causes. Benign paroxysmal positional vertigo (see links below) is the most common . Meniere 's disease , acute labyrinthitis , acoustic neuroma, and an impairment of cerebral blood flow could be additional causes of these symptoms. Given their history of cardiovascular disease, its symptoms are of some concern . If arteriosclerosis has affected the blood vessels in your brain ( it is usually in individuals with heart disease ) , its symptoms could be a sign of an impending stroke ( a stroke involving the base of your brain ) . Although benign paroxysmal positional vertigo is statistically the most likely cause of your dizziness , it would be wise to see your doctor to rule out a more serious case .
