@health.coach016: What’s Really Causing Your Shoulder Pain When You Lift Your Arm? Why does your shoulder hurt when you raise your arm, reach overhead, or lie on your side? The answer may involve your rotator cuff. This 3D medical animation explores how the supraspinatus, infraspinatus, teres minor, and subscapularis work together to move and stabilize the shoulder—and why irritation or injury can lead to shoulder pain, weakness, and difficulty with overhead movement.
