Walking for too long triggers shoulder pain, most likely because of cervical spine disease. In the process of walking, the entire spine is subjected to relatively large pressure and shape changes, if the walking speed is relatively fast, the habit of walking with the body leaning forward, the physiological bending of the cervical and lumbar spine will be reduced or even disappear because of the walking action, which can easily lead to diseases of the cervical and lumbar spine. If the symptoms have been suffering from cervical spine disease, such as cervical spondylosis, cervical disc herniation, etc., in the process of walking for a long time, the shape of the cervical spine changes, will increase the degree of compression of the soft tissue around the cervical spine. If the nerve roots of the cervical spine are stimulated, it will trigger pain symptoms in the nerve distribution area. The nerves of the cervical spine are distributed in the neck, shoulders, back, front chest, arms and palms, so people who have such symptoms are likely to be patients with cervical spine diseases.
