Shoulder Pain

Shoulder pain is a symptom, not a diagnosis. Remix Medical's Houston pain physicians identify the responsible structure — cuff, capsule, joint, or cervical spine — and treat it directly.

Key takeaways

Shoulder pain is a symptom, not a diagnosis — treating it well begins with naming the responsible structure: rotator cuff, capsule, glenohumeral or AC joint, bursa, labrum, or the cervical spine.
Rotator cuff disorders are the most common cause in adults, but frozen shoulder (adhesive capsulitis, strongly linked to diabetes), joint arthritis, bursitis, and labral tears each present differently and need different treatment.
The neck is a frequently missed source: cervical radiculopathy refers pain into the shoulder and arm, and pain radiating below the elbow with numbness or tingling points to the spine rather than the shoulder.
Diagnosis rests on a structured exam that separates cuff from capsule from joint from cervical spine, with ultrasound enabling real-time tendon assessment and precise guided injection.
Activity modification and physical therapy are first-line for most shoulder pain; targeted ultrasound-guided injections, suprascapular or cervical nerve blocks, and orthopedic referral for full tears round out care — while deformity after a fall or a hot swollen shoulder with fever needs urgent evaluation.

The shoulder is the most mobile joint in the body, and it pays for that mobility with instability and a long list of things that can go wrong. Cuff, capsule, joint, bursa, labrum, and cervical spine each produce a different pattern, and each responds to different treatment. At Remix Medical in Houston, our pain management physicians work out which structure is driving your pain before treating it.

What Causes Shoulder Pain?

The shoulder is a shallow ball-and-socket joint held together largely by soft tissue: the rotator cuff, the labrum, the joint capsule, and the surrounding musculature. It also sits directly downstream of the cervical spine, which means a neck problem can present as shoulder pain and frequently does.

Effective treatment depends on identifying which of these structures is generating the pain.

Common Causes of Shoulder Pain

1. Rotator Cuff Disorders

Impingement, tendinopathy, and tearing. The most common cause of shoulder pain in adults.

2. Adhesive Capsulitis (Frozen Shoulder)

The joint capsule thickens and contracts, producing profound stiffness alongside pain. Strongly associated with diabetes.

3. Glenohumeral or AC Joint Arthritis

Degenerative change in the main joint or in the smaller acromioclavicular joint at the top of the shoulder.

4. Bursitis

Inflammation of the subacromial bursa, the fluid-filled cushion overlying the cuff.

5. Labral Tears and Instability

More common in younger, athletic patients, and after dislocation.

6. Cervical Radiculopathy

A compressed nerve root in the neck refers pain into the shoulder and arm. This is a spine problem wearing a shoulder disguise.

How Remix Medical Can Help

Evaluation begins with a structured examination designed to separate cuff from capsule from joint from cervical spine. Ultrasound allows real-time assessment of the tendons and permits precise, guided injection.

Treatment is then matched to the structure involved:

Approach	What it involves
Activity change + physical therapy	First-line for most shoulder pain — restores motion and strength, with in-house chiropractic and soft-tissue therapy available
Medication management	Anti-inflammatories and topical agents for symptom control
Ultrasound-guided injections	Subacromial, glenohumeral, or AC joint corticosteroid or PRP, placed precisely to calm inflammation
Nerve blocks	Suprascapular block for refractory pain and for frozen shoulder; cervical epidural or medial branch block where the neck proves to be the source
Trigger point injections	For the periscapular muscular pain that accompanies most shoulder problems
Orthopedic referral	Reserved for full tears or damage that doesn't respond

Signs & symptoms

Signs and symptoms to watch for

Pain over the outer shoulder, or deep within the joint
Night pain, particularly when lying on the affected side
Stiffness, especially loss of external rotation
Weakness with elevation or rotation
Pain radiating below the elbow with numbness or tingling (suggests a cervical source)
Clicking, catching, or a sense of the joint slipping

When to see a specialist

Should you see a specialist?

See a pain specialist if shoulder pain persists beyond six weeks, wakes you at night, or limits reaching overhead. Pain radiating below the elbow with numbness or tingling suggests a cervical spine source. Sudden severe pain with deformity after trauma requires emergency evaluation.

Frequently asked

Shoulder Pain questions, answered

What is the most common cause of shoulder pain?

The most common cause is a rotator cuff problem, followed by tendinitis, bursitis, and arthritis. In older adults, wear of the cuff and joint leads the list.

When should I worry about shoulder pain?

See someone promptly if the pain follows a fall with visible deformity or you can't lift the arm, or if the shoulder is hot, swollen, and red with fever.

Will shoulder pain go away on its own?

Mild strains often settle with rest, ice, and gentle movement over a couple of weeks. Pain that lingers past that, or comes with weakness, deserves an evaluation before it worsens.

Why does my shoulder hurt more at night?

Night pain is common with rotator cuff problems, because lying down shifts pressure onto the inflamed tendons. Steadily worsening night pain is a reason to get it checked.

How is shoulder pain treated without surgery?

Most shoulder pain improves with physical therapy, activity changes, and anti-inflammatory measures. A targeted, image-guided injection can calm a stubborn flare and make therapy possible.

Why does the specific cause of shoulder pain matter so much?

Because shoulder pain is a symptom, not a diagnosis. The rotator cuff, joint capsule, glenohumeral and AC joints, bursa, labrum, and even the cervical spine can each generate shoulder pain — and each is treated differently. A shoulder treated generically for a year has usually not been diagnosed specifically.

Can neck problems cause shoulder pain?

Yes, and it's commonly missed. A compressed nerve root in the neck can refer pain into the shoulder and arm — a spine problem wearing a shoulder disguise. Pain radiating below the elbow with numbness or tingling points toward the neck rather than the shoulder.

What is frozen shoulder?

Adhesive capsulitis — the joint capsule thickens and contracts, producing profound stiffness (especially loss of external rotation) alongside pain. It's strongly associated with diabetes and follows a characteristic course.

How is the source of shoulder pain identified?

A structured exam separates cuff from capsule from joint from cervical spine, supported by ultrasound for real-time tendon assessment and precise guided injection, and MRI when it changes management.
