Vertigo is a sensation of spinning or dizziness that can make you feel as if you or your surroundings are moving when they are not. It is often caused by issues in the inner ear, brain, or sensory nerve pathways. Common conditions associated with vertigo include Benign Paroxysmal Positional Vertigo (BPPV), Meniere's disease, and vestibular neuritis. Symptoms of vertigo can include a loss of balance, nausea, and difficulty standing or walking. It can be triggered by head movements or changes in position. Treatment options may involve medications, physical therapy, or lifestyle changes to manage the underlying causes.
