For shoulder pain caused by poor posture, you can do chest stretching and shoulder shaking appropriately. 1. Chest stretching: maintain a good standing posture, straighten your body, keep your chest straight, stretch your elbows outward and downward bilaterally, and feel the sense of stretching in your chest. 2. Shake the shoulders: Standing posture, shoulders relaxed and sunken, bilateral shoulder rotation from back to front, arms naturally down, as if the shoulder joints in the front and back of the direction of the circle. Reverse this action, the main points are the same as before. The main point is to stretch and relax the tense and stiff muscles from different directions. Note that when the pain has just appeared or the pain is particularly intense, try to minimize the movement to reduce the pain. In the non-acute pain can be appropriate to expand the chest stretching and rocking shoulders. For shoulder pain, it is recommended to consult a specialist hospital for a clear diagnosis and follow the doctor’s instructions for treatment and exercise.
