The causes of right shoulder pain may be physiological factors, such as prolonged shoulder exercise, which can usually be improved after rest, in addition to cervical spondylosis, frozen shoulder, rotator cuff injury and other pathologic factors. 1. Cervical spondylosis: patients with cervical spondylosis will compress the nerves, resulting in shoulder pain. 2. Frozen shoulder: Frozen shoulder is an exudative inflammation in the rotator cuff, which will lead to fibrosis of the local tissues around the shoulder, also known as frozen shoulder, and this disease will lead to shoulder pain. 3. Rotator cuff injury: patients may strain the ligaments in the rotator cuff due to strenuous exercise, in this case, shoulder soreness often appears when the shoulder joint moves to a certain angle. Right shoulder pain may also be caused by other reasons, such as fasciitis, cholecystitis radiating pain, etc. It is recommended to consult a doctor in time to make a clear diagnosis and carry out targeted treatment.
