Causes of Common Shoulder Joint Pain
Did you know that your shoulder joint has the widest range of motion out of all the joints in your body?
Joints that have a wide range of motion like the shoulder, jaw (TMJ) and hips are more vulnerable to wear and tear, and dislocation. Basically, their design sacrifices stability for flexibility.
Typical shoulder pain can be caused by sprain/strain to tendons that move the joint; cartilage damage; or inflamed bursae (the cushion around the joint).
Sometimes a tendon can thicken in response to years of abnormal abrasion and get stuck under the acromion (the most lateral part of the shoulder blade) as you try to raise your arm. This condition is called shoulder impingement syndrome. Those who have it cannot raise their arm above shoulder level because the impingement serves as a mechanical barrier, and generates pain.
