Shoulder and neck pain should be on the alert for symptoms such as radiating pain in the upper limbs, numbness or loss of sensation in the upper limbs, dizziness, and impaired mobility of the shoulder joints. Shoulder and neck pain is generally considered cervical spondylosis or frozen shoulder, etc. When there are only pain symptoms, you need to be vigilant about other symptoms, to avoid simply thinking that muscle strain and other diagnostic errors and miss treatment. 1. Cervical spondylosis: When there is radiating pain, numbness or hyperalgesia in the upper limbs when there is shoulder and neck pain, consider radicular cervical spondylosis; when neck pain is combined with dizziness, vertebral artery cervical spondylosis is possible. Cervical spine X-ray, MRI and other tests can assist in the diagnosis. 2. Frozen shoulder: When shoulder and neck pain is combined with shoulder joint activity disorder, such as active and passive activities are limited, it may be caused by frozen shoulder, and generally there are no abnormal signs in X-ray examination of shoulder joint. It is suggested that patients with shoulder and neck pain should go to the hospital in time to get a clear diagnosis and regular treatment.
