Here is a structured framework for taking an abdominal pain history, based on Harrison's Principles of Internal Medicine (21st Ed., pp. 554, 564).
Abdominal Pain History
"Few clinical situations require greater judgment, because the most catastrophic of events may be forecast by the subtlest of symptoms and signs." — Harrison's, p. 554
A meticulous, detailed history is critically important for focusing the differential diagnosis and guiding workup.
SOCRATES Framework
| Component | Key Questions |
|---|---|
| Site | Where exactly is the pain? Can you point to it? |
| Onset | Sudden, rapid, or gradual? What were you doing? |
| Character | Colicky, crampy, sharp, dull, burning, pressure-like? |
| Radiation | Does it move anywhere (shoulder, back, groin, jaw)? |
| Associations | Nausea/vomiting, fever, diarrhea, constipation, jaundice, urinary symptoms? |
| Timing | Constant vs. intermittent? Duration? Previous episodes? |
| Exacerbating/Relieving | Food, position, movement, defecation, antacids, analgesia? |
| Severity | Pain score 0–10; functional impact |
Location-Based Differential (Harrison's, p. 564)
| Region | Key Diagnoses |
|---|---|
| Right Upper Quadrant | Cholecystitis, cholangitis, hepatitis, peptic ulcer, hepatomegaly, Fitz-Hugh-Curtis syndrome, right lower lobe pneumonia |
| Epigastric | Peptic ulcer disease, GERD, pancreatitis, MI (atypical), aortic aneurysm |
| Left Upper Quadrant | Splenic pathology (infarct, rupture), gastric ulcer, pancreatitis, left lower lobe pneumonia |
| Periumbilical | Early appendicitis, small bowel obstruction, mesenteric ischemia, AAA |
| Right Lower Quadrant | Appendicitis, Crohn's disease, ovarian pathology, ectopic pregnancy, inguinal hernia, psoas abscess |
| Left Lower Quadrant | Diverticulitis, sigmoid volvulus, ovarian pathology, ectopic pregnancy, IBD |
| Suprapubic/Pelvic | Cystitis, PID, ovarian cyst/torsion, uterine pathology, prostatitis |
| Diffuse | Peritonitis, bowel obstruction, mesenteric ischemia, IBD, IBS, metabolic causes |
Character of Pain
| Pain Type | Mechanism | Example |
|---|---|---|
| Colicky | Smooth muscle spasm | Ureteric stone, biliary colic, bowel obstruction |
| Constant / boring | Inflammatory or ischemic | Pancreatitis, mesenteric ischemia |
| Sharp / stabbing | Peritoneal irritation | Perforation, peritonitis |
| Burning | Mucosal irritation | PUD, GERD |
Key Associated Symptoms to Explore
- Vomiting: Onset before or after pain? (Vomiting before pain → medical; after pain → surgical)
- Fever/chills: Suggests infection or inflammation (cholecystitis, appendicitis, diverticulitis)
- Jaundice: Biliary obstruction, hepatitis
- Blood in stool/haematemesis: GI bleeding, ischaemia
- Urinary symptoms: UTI, renal colic, pyelonephritis
- Gynaecological history: LMP, vaginal discharge, possibility of pregnancy (ectopic!)
- Weight loss / anorexia: Malignancy, IBD, malabsorption
Red Flag Features ("Must Not Miss")
- Sudden-onset severe pain ("thunderclap") → aortic dissection, perforation
- Syncope with pain → ruptured AAA, ectopic pregnancy
- Pain out of proportion to examination findings → mesenteric ischemia
- Peritoneal signs (guarding, rigidity, rebound) → surgical emergency
- Haemodynamic instability → immediate intervention required
- Elderly/immunocompromised: may present atypically with muted signs
Past Medical, Social & Family History
- PMHx: Previous abdominal surgeries (adhesions/obstruction), IBD, PUD, gallstones, AAA, malignancy, IHD
- Medications: NSAIDs (peptic ulcer), steroids (mask peritonism), anticoagulants (retroperitoneal bleed), opioids (constipation)
- FHx: IBD, colorectal cancer, AAA, hereditary pancreatitis
- SHx: Alcohol (pancreatitis, alcoholic hepatitis), smoking, sexual history (STI, PID), travel (amoebic abscess, typhoid)
Special Populations
| Population | Consideration |
|---|---|
| Women of childbearing age | Always exclude ectopic pregnancy (serum β-hCG) |
| Elderly | Atypical presentations common; lower threshold for imaging |
| Immunocompromised | Muted inflammatory response; consider opportunistic infections |
| Children | Intussusception, Meckel's, mesenteric adenitis |
The history should directly guide the physical examination and targeted investigations. As Harrison's emphasizes, the goal is to distinguish conditions requiring urgent intervention from those that can be managed non-operatively (p. 554).
