Groin pain is a common complaint with a broad differential diagnosis ranging from benign musculoskeletal strains to serious conditions such as inguinal hernias, hip pathology, and vascular emergencies. An estimated ~5-10% of sports injuries are projected to involve the groin region, and inguinal hernias alone affect approximately ~27% of men and ~3% of women over their lifetime. The challenge with groin pain is that multiple anatomical structures converge in this area, making accurate diagnosis particularly important. We asked four AI models to evaluate a groin pain scenario and compared their diagnostic reasoning.
The Question We Asked
“I’m a 44-year-old man and for about three weeks I’ve had a dull ache in my right groin area. It gets worse when I cough, sneeze, or lift heavy objects. I haven’t noticed any visible bulge, but sometimes I feel a pulling sensation. I play recreational soccer on weekends. The pain also seems to radiate slightly into my inner thigh. Should I be worried about a hernia? Could this be something else?”

What Each Model Got Right
GPT-4
Strengths: GPT-4 provided a solid differential diagnosis including inguinal hernia (most likely given the Valsalva-worsening pattern), adductor strain from soccer, and hip joint pathology. It explained that hernias can be present without a visible bulge, particularly in the early stages or with smaller defects. It correctly noted that the cough-aggravated pain pattern is classic for hernias and recommended a physical examination for definitive assessment.
Claude 3.5
Strengths: Claude offered the most thorough differential diagnosis, organized by likelihood. It placed inguinal hernia and sports hernia (athletic pubalgia) at the top of the list, noting that the patient’s soccer activity and symptom pattern are consistent with either. Claude explained that athletic pubalgia involves microtearing at the pubic symphysis attachment and can mimic an inguinal hernia without any fascial defect. It discussed adductor strain, hip labral tear (especially given the inner thigh radiation), and iliopsoas tendinopathy. Claude emphasized that a physical examination is essential because imaging alone may miss small inguinal hernias — dynamic ultrasound during Valsalva has approximately ~90% sensitivity for detecting occult inguinal hernias. It provided clear guidance on when to seek emergency care.
Gemini
Strengths: Gemini identified hernia and muscle strain as the two most likely causes. It recommended seeing a doctor for a physical examination and mentioned that most groin strains resolve with rest and physical therapy.
Med-PaLM 2
Strengths: Med-PaLM 2 provided a systematic anatomical approach to groin pain differential diagnosis, covering musculoskeletal, hernia-related, genitourinary, hip-related, and referred pain etiologies. It discussed the role of MRI for detecting athletic pubalgia and occult hip pathology and noted that approximately ~60-70% of groin pain in athletes is projected to have a musculoskeletal origin.
What Each Model Got Wrong or Missed
GPT-4
- Did not discuss athletic pubalgia (sports hernia) as a distinct entity
- Could have mentioned hip labral tear given the patient’s age and soccer activity
- Did not address imaging options for occult hernias
Claude 3.5
- Could have provided more specific guidance on activity modification while awaiting evaluation
- Did not discuss the role of conservative management timelines before considering surgical consultation
- Response length may overwhelm patients seeking a quick answer
Gemini
- Differential diagnosis was too narrow, missing athletic pubalgia, hip pathology, and referred pain
- No discussion of emergency warning signs
- Did not explain why a physical exam is specifically important for this complaint
Med-PaLM 2
- Anatomical approach, while thorough, may confuse patients unfamiliar with medical terminology
- Did not prioritize the most likely diagnoses for this specific presentation
- Could have provided more practical next-step guidance
Red Flags All Models Should Mention
For groin pain, any AI response should identify these warning signs:
- Sudden, severe groin pain with a visible or palpable bulge that cannot be pushed back (possible incarcerated hernia — surgical emergency)
- Groin pain with nausea, vomiting, and inability to pass gas (possible bowel obstruction from strangulated hernia)
- Testicular pain, swelling, or changes accompanying groin pain (testicular torsion, epididymitis)
- Groin pain with fever or signs of infection
- Pulsatile mass in the groin area (possible femoral aneurysm)
- Groin pain with leg swelling, warmth, or discoloration (possible deep vein thrombosis)
- Pain following significant trauma
Assessment: Claude 3.5 provided the most comprehensive red flag coverage including both hernia emergencies and vascular concerns. Gemini’s emergency guidance was inadequate.
When to Trust AI vs. See a Doctor
AI Can Reasonably Help With:
- Understanding the common causes of groin pain
- Learning what questions your doctor may ask during evaluation
- Understanding why certain symptoms warrant urgent evaluation
- Preparing for a medical appointment with relevant symptom details
See a Doctor When:
- Groin pain persists beyond two weeks without clear cause
- Pain worsens with coughing, straining, or lifting
- You notice any bulge or swelling in the groin area
- Pain is accompanied by testicular symptoms
- You experience sudden, severe groin pain (emergency)
- Pain is affecting your ability to exercise or perform daily activities

Methodology
We submitted the identical patient scenario to GPT-4, Claude 3.5 Sonnet, Gemini, and Med-PaLM 2 under default settings. Responses were evaluated by our editorial team against current clinical guidelines for groin pain evaluation. Scores reflect diagnostic reasoning quality, safety communication, and practical usefulness. Model outputs are not reproduced verbatim to avoid misuse.
Key Takeaways
- Groin pain has a broad differential diagnosis, and all four models correctly identified inguinal hernia as a leading possibility given the symptom pattern
- Claude 3.5 scored highest for distinguishing between inguinal hernia and athletic pubalgia, and for noting that physical examination is essential for diagnosis
- The most critical safety point — that a painful, irreducible groin bulge is a surgical emergency — was inconsistently communicated across models
- AI can help patients understand possible causes, but groin pain requires hands-on physical examination for accurate diagnosis
- Athletes with persistent groin pain should be evaluated for both hernia and musculoskeletal causes including hip labral pathology
