How should groin pain be evaluated and managed in a 30‑year‑old male?

Evaluation and Management of Groin Pain in a 30-Year-Old Male

Begin with a systematic physical examination focusing on four key musculoskeletal categories—adductor, pubic, inguinal, and iliopsoas-related pain—while simultaneously excluding serious pathology and competing diagnoses from the hip joint, lumbar spine, and genitourinary system. 1

Initial Exclusion of Red Flags

Before pursuing musculoskeletal diagnoses, you must exclude serious pathological conditions that can present as groin pain 2:

• Genitourinary pathology: Perform a thorough scrotal examination to rule out testicular torsion, testicular mass, epididymitis, orchitis, inguinal hernia, or Fournier gangrene 2
• Neurologic conditions: Screen for neurologic abnormalities including multiple sclerosis, Lyme disease, or nerve entrapment 2
• Serious hip pathology: Consider stress fractures, infections, tumors, or slipped capital femoral epiphysis 3
• Competing diagnoses: Evaluate for lumbar spine pathology, obstructing ureteral stones, or referred pain 2

Systematic Physical Examination Approach

Four Primary Musculoskeletal Categories

Perform direct palpation and specific testing for each category 1:

1. Adductor-related pain: Palpate adductor tendons at pubic insertion; perform adductor squeeze test at 90° hip flexion (sensitive at 85.4% but not specific) 4

2. Pubic-related pain: Palpate pubic symphysis and pubic aponeurosis for tenderness 4

3. Inguinal-related pain: Palpate inguinal canal and assess for posterior abdominal wall weakness 1

4. Iliopsoas-related pain: Palpate iliopsoas insertion and assess hip flexion strength 1

Hip Joint Assessment

Perform the FADIR (flexion-adduction-internal rotation) test—a negative test helps rule out hip-related pain, though its clinical utility is limited due to poor specificity. 3 The three most common hip conditions in this age group are 3:

• Femoroacetabular impingement (FAI) syndrome
• Acetabular dysplasia and/or hip instability
• Labral, chondral, or ligamentum teres pathology without distinct osseous morphology

Pelvic Floor Assessment

Perform digital palpation of pelvic floor muscles transrectally to identify tenderness suggesting pelvic floor myalgia. 2 With the patient bending forward or lying laterally with knees bent, palpate the anterior levator ani, posterior levator ani, and obturator internus muscles through transrectal approach 2.

Laboratory and Imaging Studies

Initial Laboratory Work

Obtain urinalysis and mid-stream urine culture 2. If hematuria is present (≥3 RBCs per high-power field), perform risk-stratified hematuria evaluation 2.

Imaging Strategy

Imaging should always be combined with symptoms and clinical signs—never use imaging in isolation. 3

For Suspected Hip Pathology:

• Obtain AP pelvis and lateral femoral head-neck radiographs first 3
• Add MRI/MRA or CT scan when three-dimensional morphological assessment is needed or to evaluate intra-articular structures (labrum, cartilage, ligamentum teres) 3

For Adductor or Pubic Pain:

• Obtain pelvic MRI if diagnosis is unclear or symptoms persist after initial conservative management 1
• Combined MRI findings plus pubic aponeurosis tenderness have 92.8% post-test probability for pubic aponeurosis injury 4

For Inguinal Pain:

• Perform dynamic ultrasonography to rule out true hernia and evaluate posterior abdominal wall weakness 1

Management Algorithm

Adductor-Related and Pubic-Related Pain

Initiate active, supervised physical therapy as first-line treatment. 1 This is the recommended initial approach for both conditions.

Inguinal-Related Pain Without Hernia

Start physical therapy focusing on core strengthening and neuromuscular rehabilitation 1.

Iliopsoas-Related Pain

Obtain hip radiography and MRI given frequent concomitant hip pathology, then direct treatment based on findings 1.

Pelvic Floor Myalgia

Refer for pelvic floor physical therapy 2.

Psychosocial Assessment

Actively discuss anxiety, depression, major life stress, and impact on quality of life and daily functioning. 2 Build trust by acknowledging the real nature of their pain, demonstrate active listening by summarizing symptoms and their impact, and validate concerns 2. This is critical as chronic pelvic pain commonly coexists with psychosocial symptoms.

Key Clinical Pitfalls

• Do not rely solely on clinical tests: Most have good sensitivity but poor specificity 3
• Recognize multiple coexisting pathologies: Many patients have overlapping conditions spanning multiple anatomical regions 5
• Do not miss competing diagnoses: Hip-related pain can coexist with other types of groin pain and may be difficult to distinguish 3
• Consider referral thresholds: Neurologic, musculoskeletal, or orthopedic abnormalities warrant specialist referral 2
• Scrotal ultrasound is not always necessary: When comprehensive scrotal examination provides unambiguous diagnosis, imaging may be deferred unless acute surgical pathology is suspected 2
