Shoulder Pain: Diagnosis & Non-Surgical Relief in Phoenix

Understanding the Anatomy of the Shoulder

The shoulder is a complex joint made up of bones, muscles, tendons, and ligaments that allow for a wide range of motion.

Key components of the shoulder include:

  • Glenohumeral joint – the ball-and-socket joint formed by the humerus (upper arm bone) and the glenoid (part of the scapula).

  • Rotator cuff – a group of four muscles and tendons that stabilize the shoulder.

  • Labrum – a ring of cartilage that deepens the socket and provides support.

  • Bursa – fluid-filled sacs that reduce friction between soft tissues.

  • Acromioclavicular (AC) joint – connects the collarbone to the top of the shoulder blade.

Common Symptoms of Shoulder Pain

Shoulder pain may develop suddenly or gradually. Understanding your symptoms helps narrow down the underlying cause.

Common symptoms include:

  • Pain with reaching overhead or behind your back

  • Night pain, especially when lying on the affected side

  • Weakness or fatigue with lifting

  • Clicking, catching, or popping in the joint

  • Limited range of motion

  • Shoulder instability or the sensation of “slipping out of place”

Shoulder Pain vs. Pain from the Neck

Not all shoulder pain originates from the shoulder itself. Sometimes, pain is referred from the cervical spine.

Signs your pain may be coming from the neck include:

  • Tingling, numbness, or radiating pain down the arm

  • Pain that worsens with neck movements

  • Weakness in the hand or forearm

  • Symptoms that follow a nerve root distribution

If you're experiencing these symptoms, a pinched nerve in the neck (cervical radiculopathy) may be the true source of discomfort. Dr. Sobel performs detailed evaluations to distinguish between shoulder-origin pain and neck-related nerve pain.

Common Causes of Shoulder Pain

Frozen Shoulder (Adhesive Capsulitis)

Stiffness and pain that limit movement, often developing gradually and resolving slowly. Common in people over 40, especially women and diabetics.

Calcific Tendinitis

Calcium deposits build up in the tendons of the rotator cuff, leading to inflammation and sudden, intense pain.

Shoulder Bursitis

Inflammation of the bursa from overuse or repetitive motion. Causes pain and tenderness on the outer shoulder.

Rotator Cuff Tendinitis or Tears

Ranges from mild inflammation to full-thickness tears. Pain is often worse with overhead activity or at night.

Shoulder Instability

Can result from trauma or ligament laxity. Causes slipping or dislocation of the shoulder joint.

Labral Tears

Damage to the cartilage ring in the socket causes pain, popping, and instability, especially in athletes.

Osteoarthritis (OA) of the Glenohumeral Joint

Degenerative joint disease that causes deep, aching pain, stiffness, and reduced range of motion.

Frequently Asked Questions (FAQs)

How can I tell if my shoulder pain is from a rotator cuff tear?
Rotator cuff tears often cause weakness with lifting, especially overhead, along with pain at night. Imaging such as an ultrasound or MRI can confirm the diagnosis.
Should I get an MRI right away for shoulder pain?
Not always. A careful clinical evaluation often guides diagnosis. Imaging may be reserved for persistent or severe symptoms.
Can frozen shoulder go away on its own?
Yes, but it may take a year or more. Treatment can significantly reduce recovery time and improve mobility.
What are the benefits of ultrasound-guided injections?
Ultrasound allows precise targeting of inflamed structures, improving effectiveness and reducing the risk of complications.
How do I know if my shoulder pain is from my neck?
Neck-related pain is often accompanied by numbness, tingling, or symptoms that worsen with head movement. A thorough evaluation helps clarify the source.
