The painful parts caused by cervical spondylosis are related to the compressed nerve roots and cervical intervertebral discs, which can generally involve the back of the neck, scapula, shoulder, forearm of the upper arm and hand as follows: 1. Posterior cervical pain: pain in the posterior cervical region, especially around the nipple and auricle, is mostly related to the involvement of cervical 3 nerve roots, generally due to the compression of nerves by cervical 2/3 disc herniation. 2. Scapular region: pain in the scapular region, especially in the scapulothoracic muscles, usually due to the involvement of cervical 4 nerve roots, mostly due to cervical 3/4 intervertebral disc herniation, which may be accompanied by radiating pain in the anterior chest. 3. Shoulder: Shoulder pain is mostly due to cervical 5 nerve root involvement, and may have obvious pain at the deltoid muscle, usually accompanied by deltoid muscle weakness and atrophy. 4. Upper arm, forearm and hand: with cervical 6 nerve root involvement, the pain is mainly located in the upper arm, which can cause decreased biceps muscle strength and biceps reflexes, and the pain can also radiate to the distal thumb and finger. Cervical 7 nerve root involvement mainly involves the dorsal forearm and may radiate to the middle finger. Cervical 8 nerve root involvement mainly causes pain in the hand, and there may be weakness of the flexor muscles and interosseous muscles of the hand. The range of pain caused by cervical spondylosis is different according to the different compressed nerve roots and manifested in different segments, but due to the presence of radiating pain can make the localization of deviation, it is recommended that the patient timely hospital consultation, improve the examination, and clarify the diagnosis.
