Shoulder pain includes any pain that arises in or around your shoulder.
Shoulder pain may originate in the joint itself, or from any of the many
surrounding muscles, ligaments or tendons. Shoulder pain usually worsens

and conditions affecting structures in your chest or abdomen, such as
heart disease or gallbladder disease, also may cause shoulder pain. Shoulder
pain that arises from some other structure is called "referred pain."
Referred shoulder pain usually doesn't worsen when you move your shoulder.
Your shoulder is made up of several joints combined with tendons and muscles
that allow a great range of motion in your arm. Because so many different
structures make up the shoulder, it is vulnerable to many different problems.
The rotator cuff is a frequent source of pain in the shoulder.
The rotator cuff is a common source of pain in the shoulder. Pain can be
the result of:
Tendonitis - The rotator cuff tendons can be irritated or damaged; Bursitis
- The bursa can become inflamed and swell with more fluid causing pain;
Impingement - When you raise your arm to shoulder height, the space between
the acromion and rotator cuff narrows. The acromion can rub against (or

myofascial trigger points may cause shoulder pain.
