Management of Severe Shoulder Pain
Start with ibuprofen 400 mg every 4-6 hours combined with immediate gentle range-of-motion exercises focusing on external rotation and abduction—this dual approach addresses both pain control and prevents the catastrophic complication of adhesive capsulitis that occurs in up to 72% of immobilized shoulders. 1, 2
Immediate First Steps (Day 1)
Pain Control
- Prescribe ibuprofen 400 mg every 4-6 hours as needed for pain relief 3
- Ibuprofen taken before bedtime specifically improves sleep quality and is superior to acetaminophen for rotator cuff-related pain 1
- Use the lowest effective dose for the shortest duration; doses above 400 mg show no additional analgesic benefit 3
- Apply ice before each exercise session for symptomatic relief 1
Critical Physical Examination Findings
- Look for a painful arc between 60-120° of abduction/flexion—this is pathognomonic for subacromial pathology (rotator cuff or bursal inflammation) 1
- Assess muscle tone, strength, soft tissue changes, joint alignment of the shoulder girdle, and pain levels 4, 1
- Normal rotator cuff strength rules out full-thickness tear 1
Imaging Decision
- Obtain upright three-view radiographs (AP internal/external rotation plus axillary or scapula-Y view) immediately if trauma is involved 2
- The axillary or scapula-Y views are essential—dislocations are frequently missed on AP views alone 2
- Reserve MRI for cases where conservative management fails after 3-4 weeks 2
First-Line Treatment Protocol (Weeks 1-3)
Exercise Prescription (Mandatory to Prevent Frozen Shoulder)
- Begin gentle passive and active-assisted range of motion exercises immediately, placing the arm in safe positions within the patient's visual field 4, 1
- Focus specifically on external rotation and abduction movements to address the impingement mechanism 4, 1
- Increase active range of motion gradually while simultaneously restoring proper shoulder alignment and strengthening weak muscles in the shoulder girdle 4, 1
- Early mobilization is mandatory—static positioning or delayed mobilization leads to adhesive capsulitis (frozen shoulder) in up to 72% of patients with prolonged immobilization 4, 2
Critical Pitfall to Avoid
- Never allow the patient to sleep on the affected shoulder 1
- Avoid static positioning or strapping of the upper extremity, as evidence for preventing loss of range of motion or pain is not well established 4, 1
Progression Phase (Weeks 4-8)
- Advance to intensive strengthening exercises targeting rotator cuff and scapular stabilizers 1
- Emphasize posterior shoulder musculature strengthening and address any scapular dyskinesis 1
- Implement a graduated return to overhead activities with proper mechanics 1
Adjunctive Interventions When First-Line Fails
Corticosteroid Injection
- Use subacromial corticosteroid injection when pain is clearly related to rotator cuff or bursa inflammation 4, 1
- This is appropriate when conservative management with NSAIDs and exercises has not provided adequate relief 4
Botulinum Toxin (Specific Indication)
- Inject botulinum toxin into the subscapularis and pectoralis muscles if shoulder pain is thought to be related to spasticity (typically in hemiplegic or post-stroke patients) 4
Advanced Imaging
- Obtain ultrasound evaluation to assess for structural pathology if not improving after 3-4 weeks 1
- MR arthrography is the gold standard when soft-tissue injury is suspected, superior to noncontrast MRI for diagnosing labral tears and partial rotator cuff tears 2
When to Refer to Orthopedic Surgery
- If no improvement after 3-4 weeks of conservative management, consider advanced imaging and specialist referral 1, 2
- Unstable or significantly displaced fractures require acute surgical management 2
- Joint instability (glenohumeral or acromioclavicular dislocation) typically requires acute surgical treatment 2
- Traumatic massive rotator cuff tears may require expedited surgical timeline to achieve optimal postoperative functional outcomes 2
Special Consideration: Complex Regional Pain Syndrome (CRPS/Shoulder-Hand Syndrome)
Diagnosis
- Diagnose based on pain and tenderness of metacarpophalangeal and proximal interphalangeal joints, associated with edema over the dorsum of fingers, trophic skin changes, hyperaesthesia, and limited range of motion 4
- Triple phase bone scan demonstrates increased periarticular uptake in distal upper extremity joints 4
Treatment
- Start oral corticosteroids at 30-50 mg daily for 3-5 days, then taper over 1-2 weeks to reduce swelling and pain 4
- Active, active-assisted, or passive range of motion exercises prevent CRPS development 4
Key Safety Warnings for NSAIDs
- Increased risk of bleeding, ulcers, and gastrointestinal perforation—risk increases with longer use, higher doses, smoking, alcohol, older age, and concurrent use of corticosteroids or anticoagulants 3
- Do not use after 30 weeks of pregnancy; monitor if used between 20-30 weeks 3
- Avoid in patients with history of asthma attack or allergic reaction to aspirin or other NSAIDs 3
