The shoulder is a complex structure consisting of three bones, the joints between them, and the muscles that generate its strength and motion. Everything from scratching your back to lifting a book requires the use of your shoulder. The shoulder has the largest amount of motion of any joint in the body. Because of this, it is often subject to excessive strain leading to pain and tissue injury. Shoulder problems can be caused by overuse, traumatic injury, and/or changes that occur naturally in your body.

How Your Shoulder Works
The shoulder consists of three bones: the shoulder blade (scapula), the collarbone (clavicle), and the upper arm bone (humerus). The shoulder blade and the collarbone come together on top of the shoulder to form the acromioclavicular (AC) joint. The upper arm bone is shaped like a ball to fit neatly into a shallow socket on the shoulder blade, referred to as the glenohumeral joint. The socket is shallow to allow a wide range of motion of the arm. Inside the socket is a flexible rim of soft tissue called the labrum, which helps increase the stability of the shoulder.
Surrounding the shoulder joint is a group of four muscles that help to rotate the arm and provide additional stability. Together, these muscles form the rotator cuff. There are many other muscles that help move the shoulder, such as the pectoralis muscles (pecs) on the chest or the latissimus dorsi (lats) on the back. In order for the shoulder to function properly, the bones, joints and muscles must all work in unison.
Evaluating Shoulder Pain
Evaluation for shoulder pain starts with you giving us a history of your problem: when and how it started, how it currently feels, and which treatments you have tried so far. We also ask you about other medical conditions that may contribute to your shoulder pain. We do a physical exam to test the structures of your shoulder. We check your shoulder’s range of motion and strength and do special tests that can uncover specific problems.
Based on the findings of your physical exam, we may recommend a cortisone injection as both a clinical test and treatment for your pain. The numbing medicine mixed in the injection helps us determine the source of your pain, whereas the cortisone medication of the injection can provide pain relief. Sometimes we order tests such as x-rays or MRIs to visualize your bones and soft tissues. X-rays can show us things like fractures, spurs, and changes from arthritis. MRIs can show us more detail of the bones, as well as soft tissue damage like tears of the rotator cuff or labrum. In some cases, we need input from other specialists, particularly Neurologists – who can evaluate and test the nerve supply to the shoulder.
Whatever the cause of your shoulder pain, we are dedicated to helping you find the best treatment. Request an appointment today.
Causes of Shoulder Pain
- Bone Spurs
- Less common causes – infection, tumors, or nerve problems
Treating Shoulder Pain
Treatment of shoulder pain is very specific to the diagnosis and severity of your symptoms.
Surgery may be the next option for certain shoulder conditions if all other treatment options have been exhausted. Although many surgeries can be done through small incisions using a special camera to see inside the body (arthroscopy), some may still require a traditional open surgery.
