The common cause of pain between the shoulder and neck is trapezius strain, which connects the cervical vertebrae with the shoulder and can lift the scapulae, causing lateral flexion and rotation of the neck. Long-term ambulatory work or study can cause the cervical spine to tilt forward and cause strain on the trapezius muscle to maintain a normal posture of the cervical spine, resulting in limited neck movement and trapezius pain. When pushing the shoulder during fitness exercise, such as the barbell is too heavy, it will also cause the trapezius muscle to borrow the force and shrug the shoulder, which will cause strain pain in the trapezius muscle, and when pressing the trapezius muscle, there will be obvious pain and spastic nodes can be touched.
