As the most mobile joint in the body, our shoulders have the ability to rotate, swing, reach, lift, extend, etc. However, with this wide range of motion comes the instability despite the shoulders having a series of muscles, ligaments, and tendons supporting it. Most of the time, shoulder pain can be a result of strain, tendonitis, shoulder joint instability, dislocation, fractures, or pinched nerves. These conditions can be caused by extraneous activities, distress, or even other medical reasons.
