Shoulder pain means the physical discomfort of the shoulder, including the joint itself or the muscles, tendons and ligaments that support the joint.The shoulder has a wide and versatile range of motion. When something goes wrong with your shoulder, it hampers your ability to move freely and can cause a great pain and discomfort.
You can injure your shoulder by performing manual labor, playing sports, or even by repetitive movement. Certain diseases can bring about pain that travels to the shoulder. These include diseases of the cervical spine (neck), as well as liver, heart, or gallbladder disease.
This is a condition characterized by swollen tendons. Another common cause of shoulder pain is impingement syndrome where the rotator cuff gets caught between the acromium (part of the scapula that covers the ball) and humeral head (the ball portion of the humerus).
