Why do you have vertigo only when walking not when sitting?

Vertigo experienced while walking but not sitting may be due to a vestibular system issue, which affects balance and spatial orientation. When standing or walking, the brain receives conflicting signals from the inner ear, vision, and proprioception, leading to a sensation of dizziness. In a seated position, the body is more stable, reducing the sensory conflict and allowing for better balance. Additionally, factors like inner ear disorders, medication side effects, or even anxiety can contribute to this specific experience of vertigo.
