The symptoms that can be clearly identified as cervical spondylosis are the following, and anyone who has one of the following indicates that he or she has cervical spondylosis. 1.Pain in the back of the neck can be alleviated by tugging the head and neck upward with the hand, but aggravated by putting pressure downward (mostly cervical cervical spondylosis). 2.The pain in the neck is accompanied by radioactive pain or numbness in the upper limbs (including the hands) (mostly cervical spondylosis of the nerve root type). 3.When the eyes are closed, the head and neck are rotated to the left and right, triggering migraine or vertigo (mostly vertebral artery cervical spondylosis). 4.When neck pain is accompanied by muscle weakness and muscle pain in the upper or lower limbs (mostly spinal cord cervical spondylosis or combined cervical spinal stenosis). 5.When lowering the head, the whole body suddenly becomes numb or has an “electric shock”-like sensation (mostly spinal cord cervical spondylosis, especially in combination with severe cervical spinal stenosis). Unlike the previous ones, those who have one or two of the following symptoms may only suffer from cervical spondylosis, and further examination is needed for a clear diagnosis. 1.Simple neck discomfort with an uncomfortable feeling when the neck is placed in any position (probably cervical type). 2.Unexplained numbness in the upper extremities, especially if the fingertips are obvious (may be spinal nerve root type). 3.Persons with radiating pain in the fingers (probably spinal nerve type). 4.There is a feeling of banding on the body, i.e., as if the body is entangled with a cloth belt (probably spinal cord type). 5.Suddenly kneeling down when walking, or a feeling of “drifting” in the legs when walking (may be spinal cord type). 6.Sudden drop of the object in the hand (may be spinal cord type). 7. “Heart disease” with a normal electrocardiogram and “stomach disease” with no abnormality in internal medicine examination (possibly vertebral artery type). 8. Difficulty in swallowing with neck pain (probably dysphagia).
