Treatment of Rib Pain
Start with scheduled acetaminophen every 6 hours as first-line treatment, add NSAIDs like ibuprofen or ketorolac for inadequate pain control, and combine with non-pharmacological measures including ice application and breathing exercises. 1, 2
Initial Clinical Assessment
Before initiating treatment, determine if the rib pain represents a benign condition or requires urgent evaluation:
Reassuring features that suggest musculoskeletal origin include:
- Pain that varies with respiration, body position, or food intake 1
- Well-localized tenderness on the chest wall 1
- Pain reproduced by palpation, breathing, turning, twisting, or bending 1
Red flags requiring immediate evaluation:
- Symptoms interrupting normal activity with cold sweats, nausea, vomiting, or fainting 1
- Sudden worsening of chest pain, increasing shortness of breath, or fever 2
- Age >60 years, oxygen saturation <90%, or anticoagulation therapy 2, 3
Pharmacological Management Algorithm
First-Line: Acetaminophen
- Administer acetaminophen 1000 mg every 6 hours on a scheduled basis (not as-needed dosing) 1, 2
- Oral formulations are equally effective as intravenous for pain control 2
- Scheduled dosing provides superior pain control compared to PRN administration 2
Second-Line: NSAIDs
When acetaminophen alone provides insufficient relief:
- Add ibuprofen 400 mg every 4-6 hours (maximum 3200 mg/day, though doses above 400 mg show no additional benefit for acute pain) 4
- Alternatively, use ketorolac 60 mg IM initially for severe pain (maximum 120 mg/day for patients 17-64 years) 3
Critical contraindications to avoid:
- Aspirin/NSAID-induced asthma 1, 3
- Active peptic ulcer disease or GI bleeding 4
- Pregnancy or cerebrovascular hemorrhage 3
- Severe renal impairment 1
Third-Line: Ketamine (Opioid Alternative)
- Low-dose ketamine 0.3 mg/kg IV over 15 minutes provides analgesia comparable to morphine but with more psycho-perceptual side effects 1, 2
- Consider for severe pain when NSAIDs are contraindicated or ineffective 1
Non-Pharmacological Interventions
Implement these measures alongside medications:
- Apply ice or cold compresses to the painful area for 15-20 minutes several times daily 1, 2
- Encourage deep breathing exercises and incentive spirometry to prevent atelectasis 5
- Gentle mobilization and avoiding prolonged immobilization 1
Advanced Interventional Options
For refractory pain despite multimodal therapy:
Regional anesthesia techniques (considered gold standard for severe cases):
Manual manipulation techniques may benefit specific mechanical rib dysfunctions, particularly in painful rib syndrome or slipping rib syndrome 6
Diagnostic Imaging Considerations
Chest radiography is the initial imaging test to exclude fractures, pneumothorax, or other serious pathology 1
Important caveats:
- Standard chest X-rays miss up to 50% of rib fractures, but treatment remains unchanged 1, 2
- Dedicated rib series or point-of-care ultrasound can detect fractures missed on chest X-ray 1
- CT chest should be reserved for suspected malignancy or when pulmonary disease evaluation is needed 1
Special Clinical Scenarios
Painful Rib Syndrome (Musculoskeletal)
This benign condition presents with:
- Pain in lower chest or upper abdomen with tender spot on costal margin 7
- Pain reproduced by pressing the tender spot 7
- No investigation required beyond clinical diagnosis 7
- Reassurance about the benign nature is the most critical intervention 8, 7
Twelfth Rib Syndrome
- Conservative treatment with heat/ice, rest, and oral analgesics as first-line 9
- Intercostal nerve blocks for persistent symptoms 9
- Surgical rib resection for refractory cases 9
Rib Fractures
Risk stratification determines intensity of management:
- Multiple fractures (≥3), flail chest, or displaced fractures require aggressive pain control 2, 3
- Surgical stabilization should be considered within 48-72 hours for unstable chest wall or severe displacement 2
- Healing typically occurs within 6-8 weeks, though complete recovery may take up to 2 years 2
Follow-Up and Monitoring
Schedule follow-up within 1-2 weeks for all patients with rib pain 2
Arrange earlier follow-up (3-5 days) if:
- Age >60 years 2
- Chronic lung disease or smoking history 2
- Three or more rib fractures 2
- Taking anticoagulation 2
Refer to physical therapy if pain persists beyond 4-6 weeks 2
Common Pitfalls to Avoid
- Relying solely on chest radiographs when clinical suspicion for fracture is high (50% false-negative rate) 1, 2
- Using PRN dosing instead of scheduled acetaminophen 2
- Failing to identify high-risk patients who need aggressive multimodal analgesia 2
- Ordering extensive imaging for painful rib syndrome, which is a clinical diagnosis 7
- Underestimating morbidity in elderly patients, where each rib fracture increases pneumonia risk by 27% and mortality by 19% 5
