What is an appropriate method for creating support for a shoulder injury?

Using a pillow to support under the arm is an appropriate method for creating support for a shoulder injury. This approach helps to immobilize the shoulder and reduces discomfort by providing stability to the arm. By elevating the arm with a pillow, it also helps to prevent further strain on the shoulder muscles and joints, allowing time for healing. This method ensures that the injured area is protected and supported, which is crucial in managing any injury effectively.

In situations involving shoulder injuries, it's important to minimize movement and provide adequate support, which the use of a pillow accomplishes. The other methods listed may inadvertently exacerbate the injury or cause additional discomfort, emphasizing the necessity of proper support in injury management.
