Cervical spondylosis is a painful condition resulting from the compression of the spinal cord, nerves and blood vessels after aging and degeneration of the cervical discs, vertebrae and ligaments, and hypertrophy and hyperplasia. The main manifestations are neck and shoulder pain, numbness and weakness of the upper or lower limbs, difficulty walking, and dizziness. How to self-test for cervical spondylosis? 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 relieved by pulling the head and neck upward by 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 combined with severe cervical spinal stenosis).
