Edema can occur around the cervical spine, and the structures of this lesion are relatively numerous. The most common are the soft tissues of the cervical spine, where swelling and edema occur, and the nerves, where edema is present. If there is inflammatory edema in the soft tissues of the cervical spine, it may manifest as localized pain, increased pain after activity, mild or significant localized swelling, or a feeling of tightness and stiffness in the neck. In case of edema of the cervical nerve, it may manifest as numbness or pain in the neck, shoulder, arm and palm, and the movement of the shoulder and neck may be restricted, and even the movement of the arm may be restricted to a certain extent, and once the shoulder, neck and even arm are accidentally moved, or the shoulder and neck are moved at the same time, it may aggravate the pain and cause severe pain symptoms.
