Bad lifestyle: In life, if you keep a bad posture for a long time, such as improper sleeping posture, long time head down, long time standing, improper sitting posture, etc. will cause physiological neck stiffness and dizziness symptoms. 2. Cervical spondylosis: the protruding intervertebral disc compresses the nerves and blood vessels, resulting in poor blood flow, which can cause dizziness and stiff neck muscles. 3. Neck trauma: including when the neck is sprained, heavy objects hit the head and neck, etc. can cause stiff neck, dizziness and other symptoms. 4.
