Summary
A 16-year-old boy experienced chronic pain due to femoral nerve entrapment. Surgical release provided temporary relief, but myofascial pain syndrome was identified as a cause of persistent symptoms.
Area of Science:
- Neurology
- Surgical Anatomy
Background:
- Chronic pain in adolescents can present with complex distributions.
- Femoral nerve entrapment is a potential cause of lower extremity pain.
Observation:
- A 16-year-old male presented with 16 months of continuous right testicular, groin, thigh, and knee pain.
- Pain distribution was retrograde to the suspected entrapment site.
- Tinel's sign was a key diagnostic indicator.
Findings:
- Surgical division of the Hunter's canal aponeurosis initially relieved symptoms for three days.
- A subsequent exploration found the femoral nerve to be normal.
- Relapse of pain was attributed to myofascial pain syndrome.
Implications:
- This case highlights the importance of considering myofascial pain syndrome in cases of persistent or relapsed pain, even after addressing a primary nerve entrapment.
- Accurate diagnosis and management of both primary nerve compression and secondary myofascial pain are crucial for effective treatment of chronic pain.
