Right Upper Quadrant Pain Worsened by Activity, Sneezing, and Coughing
Pain in the right upper quadrant that worsens with activity, sneezing, and coughing is most likely musculoskeletal in origin—specifically costochondritis or intercostal muscle strain—rather than visceral pathology. 1, 2
Key Diagnostic Feature: Pain Pattern
The critical distinguishing feature here is pain aggravated by movement, coughing, and sneezing, which strongly suggests a musculoskeletal rather than visceral etiology. 1, 2
- Musculoskeletal chest/abdominal wall pain reproduces with palpation over affected costochondral junctions or intercostal muscles and worsens with trunk movement, deep breathing, coughing, or sneezing. 2
- Visceral causes (gallbladder disease, hepatobiliary pathology) typically present with colicky pain unrelated to respiratory movements or positional changes. 3, 4
Primary Differential Diagnosis
Most Likely: Musculoskeletal Causes
Costochondritis is the leading consideration when RUQ pain worsens with movement and respiration. 2
- Palpation over the right costal cartilages (typically ribs 2-5, but can involve lower ribs near RUQ) elicits reproducible tenderness. 2
- Pain increases with chest wall movement, deep inspiration, coughing, or sneezing. 2
- This is a clinical diagnosis made by history and physical examination showing reproducible pain with palpation over costal cartilages. 2
Intercostal muscle strain or rib stress fracture should be considered if there is history of trauma, repetitive motion, or severe coughing. 1
- Stress fractures cause localized rib tenderness and pain with any movement that stresses the affected rib. 1
- Slipping rib syndrome (subluxation of lower ribs 8-10) can cause RUQ pain that worsens with movement. 1
Less Likely but Important: Visceral Causes
If musculoskeletal examination is negative, consider biliary and hepatic pathology, though these typically do not worsen with coughing or sneezing. 4, 5
Biliary colic or cholecystitis presents with colicky RUQ pain radiating to the back or right shoulder, often triggered by fatty meals, not by respiratory movements. 3, 4
Hepatic pathology (hepatitis, liver abscess, hepatic mass) causes constant RUQ pain with hepatic capsular stretch, occasionally worsened by deep palpation but not typically by coughing. 5
Pleuropulmonary causes (right lower lobe pneumonia, pulmonary embolism, pleurisy) can cause RUQ pain worsened by breathing but usually present with respiratory symptoms (dyspnea, cough, fever). 6, 7
Diagnostic Approach
Step 1: Focused Physical Examination
Palpate the right costal cartilages and intercostal spaces to reproduce the pain—this confirms musculoskeletal etiology. 2
- Press firmly over each costochondral junction from ribs 2-10 on the right side. 2
- Assess for localized tenderness, swelling, or crepitus. 1
- Have the patient perform movements that reproduce pain (trunk rotation, arm elevation, deep breathing). 1
Assess for Murphy's sign (inspiratory arrest with deep RUQ palpation)—if positive, consider biliary pathology despite atypical pain pattern. 4, 5
Step 2: Risk Stratification
In patients under 35 years without cardiac risk factors, costochondritis is a clinical diagnosis requiring no imaging if examination reproduces pain with palpation. 2
In patients over 35 years or with cardiac risk factors, obtain ECG to exclude cardiac causes even when musculoskeletal pain seems likely. 2
- Coronary artery disease is present in 3-6% of adults with chest pain and chest wall tenderness. 2
Step 3: Imaging Only If Visceral Pathology Suspected
If physical examination does NOT reproduce pain with palpation, or if there are concerning features (fever, jaundice, elevated liver enzymes), obtain right upper quadrant ultrasound as first-line imaging. 4, 5
- Ultrasound is the American College of Radiology's recommended initial imaging for RUQ pain with 96% accuracy for gallbladder pathology. 4
- Ultrasound evaluates for cholecystitis, cholelithiasis, bile duct dilatation, and hepatic abnormalities. 4, 5
Do not order imaging for typical musculoskeletal pain with reproducible tenderness on examination—this exposes patients to unnecessary cost and radiation without diagnostic benefit. 2
Treatment Recommendations
For Confirmed Musculoskeletal Pain
Treat with NSAIDs or acetaminophen as first-line therapy for costochondritis or muscle strain. 2
- Ibuprofen 400-600 mg three times daily or naproxen 500 mg twice daily (if no contraindications). 2
- Acetaminophen 650-1000 mg every 6 hours if NSAIDs contraindicated. 2
Advise activity modification—avoid movements that reproduce pain, including heavy lifting, repetitive trunk rotation, or strenuous upper body exercise. 2
Provide reassurance—costochondritis is self-limited and benign, typically resolving in weeks to months. 2
Critical Pitfalls to Avoid
Do not dismiss reproducible chest wall tenderness in older adults without cardiac evaluation—3-6% will have concurrent coronary disease. 2
Do not order CT or MRI for typical musculoskeletal pain—these are inappropriate initial tests and expose patients to unnecessary radiation and cost. 4, 5
Do not assume all RUQ pain is biliary—musculoskeletal causes are common and easily diagnosed by physical examination. 6, 7
Recognize that pain worsened by coughing/sneezing is the key feature distinguishing musculoskeletal from visceral pathology—visceral pain does not follow this pattern. 1, 2
