1.Shoulder Problems
If your shoulder hurts and you have trouble breathing or tightness in your chest, call 911 right away — those could be signs of a heart attack. You also should ask someone to drive you to the emergency room if you can’t use your shoulder to move your arm or have sudden swelling or intense pain.
2.Tests
Your doctor may want to get a closer look at the inside of your shoulder. X-rays will show any obvious injuries to the bones, and a CT scan can give a more detailed view. An MRI scan or ultrasound can show if the tissues around your shoulder are damaged.
