Wear-and-tear over time or overuse can result in:
        • Osteoarthritis, which is a wearing down of the cartilage surface that covers the bones where they meet to make a joint
          • This is the most common form of arthritis (joint inflammation)
          • Can effect not only the main shoulder joint (gleno-humeral) but also the smaller acromio-clavicular joint (between the acromion and clavicle) and sterno-clavicular joint (between the sternum and clavicle)
        • A tear of the labrum which functions as a shock absorber between the bones
        • A stress fracture of the bone
          • Scapula, glenoid, humerus bones
        • Inflammation of the tendons (tendonitis) that connect the muscles to the bones or inflammation of the associated bursal sacs (bursitis)
          • Rotator cuff (supraspinatus, infraspinatus, teres minor, subscapularis) and
            bicepts tendonitis
          • Subdeltoid/subacromial bursitis
        • Inflamation of the muscles (myositis)
          • Rotator cuff (supraspinatus, infraspinatus, teres minor, subscapularis), deltoid and bicepts myositis
        • These can all cause pain, swelling, stiffness, locking, catching, grinding, popping, fatigue, weakness, instability and deformity
