Shoulder blade pain can be confusing because the causes aren’t always obvious. This symptom can be a sign of something serious like a heart attack or lung cancer, or something as simple as sleeping wrong or poor posture at work.
The acromioclavicular joint, abbreviated as the AC joint, is the junction of the end of the collarbone (clavicle) with the side of the shoulder blade (called the acromion). The AC joint can be damaged much like other joints and may require treatment.
A shoulder separation is an injury to the acromioclavicular joint on the top of the shoulder. The shoulder joint is formed at the junction of three bones: the collarbone (clavicle), the shoulder blade (scapula), and the arm bone (humerus). A shoulder separation occurs where the clavicle and the scapula come together.
Shoulder cortisone injections have been used to treat inflammation since the late 1950’s. These shots are injected directly into the affected area, and are sometimes mixed with a local anesthetic to provide immediate relief for patients who are experiencing unbearable pain.
