How can my doctor find out I have shoulder instability?
Your doctor will look at your shoulder, moving your arm around to find signs of instability. Your doctor may also take X-rays. The X-rays will show if your shoulder bones are in the right place. Your doctor might want you to have a magnetic resonance image (MRI) scan. An MRI lets your doctor see the bones and other parts of your shoulder in greater detail.
