It : It sounds as though you have benign positional vertigo. If this dizziness is not accompanied by ringing in the ears and/or hearing loss that is the most likely diagnosis. It is thought to be caused by tiny crystals in the inner ear that have become positioned out of place. Treatment involves a series of controlled movements to reposition the "canoliths"or tiny crystals. This usually works pretty well but might have to be repeated. You don't mention how long this has been going on. A less likely cause of lightheadedness and not true spinning or vertigo can be "orthostatic hypotension", the feeling people get when they stand up fast and the blood flow to the brain is reduced because of a blood pressure drop. This usually lasts only moments. In any case. An ENT doctor can check you for these conditions.

Vertigo: Sounds like you might have benign positional vertigo, which is very common. You should consider seeing an ENT doctor.

BPPV: What you are describing is most likely bppv or benign paroxysmal positional vertigo. Best to see your doctor for evaluation and treatment.

Could be: Benign positional vertigo of if sudden over the last few days could be a viral labyrinthitis. See your doctor for an evaluation.
