Meralgia Paresthetica
Written by Dr. Jason Ngan, DC
What is Meralgia Paresthetica?
Meralgia paresthetica (aka lateral femoral cutaneous neuropathy) is a condition where the lateral femoral cutaneous nerve is compressed. The name breaks down to thigh (meros), pain (algia), abnormal (para), sensation (aisthesis). The lateral femoral cutaneous nerve originates from the L2 and L3 nerve roots, travels through the inguinal ligament (groin area) to the front and side of the thighs. This nerve only controls sensation so movement is not affected.
What Causes Meralgia Paresthetica?
There are various ways that the lateral femoral cutaneous nerve can get compressed. Some common methods include:
Tight fitting clothing/belt
Overweight/obesity
Pregnancy
Trauma (such as seat belt injury)
Diabetes (causes inflammation)
What are the Signs and Symptoms?
Pain (burning), numbness, tingling at the front and sides of the thigh
Since the lateral femoral cutaneous nerve is sensory only, there is no weakness involved.
How is Meralgia Paresthetica Diagnosed?
Meralgia paresthetica is diagnosed with a thorough medical history, physical examination, and orthopedic testing. Diagnostic imaging such as MRI, diagnostic ultrasound, and EMG/NCV can identify signs of lateral femoral cutaneous nerve entrapment.
Abnormal sensation (pain, numbness, tingling).
No muscle weakness
What are the Treatment Options?
Chiropractic manipulation and mobilization
Soft tissue therapies
Gua-sha
E-stim
Ultrasound
Clothing advice
Anti-inflammatory diet
Rehabilitative exercises and stretches
Other treatments that patients may seek (not provided at Ngan Chiropractic) include anti-inflammatory medication, nerve block, and steroid injection.
