The symptoms of dizziness and nausea when you move your neck: 1. It may be caused by vertebral artery type cervical spondylosis; 2. It may be caused by otogenic vertigo. There is a receptor in the ear called the vestibular labyrinth, which includes a semicircular canal with fine hair-like receptors on it for sensing the rotation of the head. There is also an otolithic canal in the ear, above which there are crystalline receptors that sense head movements and spatial positions. When the crystalline receptors fall off into the semicircular canal for some reason, the semicircular canal senses some movements that cannot be sensed under normal circumstances, so the symptoms of dizziness, nausea and vomiting appear when the neck is moved. If there is no relief within a short period of time, you must go to a regular hospital in time to get medical advice and choose a reasonable treatment method after the cause is clear, so as not to delay the condition.
