Dizziness and stiffness in the neck may be caused by cervical spondylosis. It is recommended to have a CT scan of the neck to determine whether it is cervical spondylosis to prevent delays and further aggravation of the symptoms. Daily attention should also be paid to avoid improper sitting posture and prolonged writing or playing with electronic products with head down, and non-steroidal anti-inflammatory drugs can be taken as prescribed by the doctor if necessary.
