Vertigo is a medical condition characterized by a sensation of dizziness or spinning. It is caused by a disruption in the inner ear, which affects balance and can lead to nausea, vomiting, and difficulty walking. VERTIGO is a common symptom of many conditions, including Meniere's disease, labyrinthitis, and benign paroxysmal positional VERTIGO. Treatment for VERTIGO typically involves medications, physical therapy, and lifestyle changes.
