Soreness in the neck, back and shoulders is mainly due to the following reasons: 1. The patient’s prolonged maintenance of a posture in daily life, or prolonged head-down work or prolonged head-down playing with the cell phone, may cause strain or injury to the cervical spine and the back of the shoulder, resulting in soreness in the neck, back and shoulders. 2. 3. It may also be due to frozen shoulder, gallbladder, gallstones, and cervical spondylosis, which can cause soreness in the neck, back, and shoulders.
