Why do I have shoulder pain?
Shoulder pain can be caused by multiple different things. It can be caused by trauma, arthritis, bursitis, dislocation, instability, and most commonly a repetitive motion in an incorrect biomechanics. When looking at repetitive use injuries, the most common culprit will be any of the rotator cuff muscles, biceps tendon, or decreased scapular mobility. It is a complex joint due to the fact that it has a big range of motion and little muscles to stabilize.
