Shoulder Pain
Rotator cuff, frozen shoulder, arthritis — and what works for each.
The shoulder is the most mobile joint in the body, which makes it powerful but also vulnerable. Most shoulder pain comes from one of four conditions: rotator cuff issues (tendinitis, partial tears, full tears), frozen shoulder, shoulder impingement, or shoulder arthritis. Each has a distinct treatment path, and accurate diagnosis is half the battle.
Understanding the Condition
What is Shoulder Pain?
The shoulder joint is a shallow ball-and-socket — the round head of the humerus sits in the small glenoid socket of the scapula. Stability comes from the rotator cuff (four small muscles and tendons), the labrum (cartilage rim of the socket), and the surrounding ligaments. The joint is also covered by bursae that allow smooth gliding.
Rotator cuff disease is by far the most common cause of shoulder pain in adults. Tears can be acute (from injury) or chronic (from gradual degeneration). Frozen shoulder is a separate condition where the joint capsule itself thickens and tightens, dramatically restricting motion. Impingement is irritation of rotator cuff tendons under the acromion bone.
Common Causes
- Rotator cuff tendinitis or tears
- Shoulder impingement
- Frozen shoulder (adhesive capsulitis)
- Shoulder arthritis (osteoarthritis or rheumatoid)
- Labral tears (SLAP, Bankart)
- Shoulder instability or dislocation
- Biceps tendinitis
- AC joint arthritis or separation
Common Symptoms
- Pain reaching overhead, behind the back, or across the body
- Night pain (especially lying on the affected side)
- Weakness lifting the arm
- Decreased range of motion
- Catching, popping, or grinding
- Visible deformity (after dislocation or fracture)
When to Seek Care
When Should You See a Specialist?
See a specialist for shoulder pain lasting over 2–4 weeks, pain that disrupts sleep, weakness lifting the arm, sudden loss of motion, or any acute injury. Inability to lift the arm at all suggests a complete rotator cuff tear and warrants prompt evaluation.
Treatment Options
How We Treat Shoulder Pain
We always begin with the least invasive treatment that's likely to work for you. Surgery is reserved for cases where conservative care has been given a fair trial — or when the situation truly requires it.
Conservative (Non-Surgical) Care
- Activity modification
- Anti-inflammatory medications
- Physical therapy focused on rotator cuff and scapular control
- Image-guided cortisone injections (subacromial or glenohumeral)
- Hyaluronic acid injections for arthritis (off-label)
- PRP for select tendon conditions
- Manipulation under anesthesia (frozen shoulder)
Surgical Options
- Arthroscopic rotator cuff repair (single- or double-row)
- Subacromial decompression for impingement
- Labral repair (Bankart, SLAP)
- Shoulder stabilization for instability
- Total shoulder replacement (anatomic or reverse)
- Biceps tenodesis for biceps tendon problems
Recovery & Outlook
What to Expect After Treatment
Frozen shoulder typically resolves in 12–18 months even without treatment, though PT speeds it up. Rotator cuff repair recovery: 4–6 months for full strength, 6–12 months for return to overhead athletic activity. Shoulder replacement: pain relief is rapid; full strength recovery takes 6–12 months.
