Meralgia paraesthetica: burning and tingling in the outer thigh — not a spinal problem

myBackPain Assessment

Burning, tingling, or numbness in your outer thigh that doesn’t seem to come from the spine?

What is meralgia paraesthetica?

Meralgia paraesthetica is caused by compression of the lateral femoral cutaneous nerve (LFCN) as it passes under or through the inguinal ligament near the hip. It produces a characteristic pattern of burning, tingling, or numbness in the outer thigh that is often mistaken for hip pathology or spinal nerve root compression. It is a peripheral nerve entrapment — not a spinal condition — and responds well to the right treatment once correctly identified.

What does it feel like?

Burning, tingling, or numbness on the outer (lateral) surface of the thigh
No back pain in most cases — the outer thigh symptoms are the primary complaint
Symptoms typically do not extend below the knee — a key distinguishing feature
Worse with standing, walking, or hip extension
Often relieved by sitting or hip flexion
May be aggravated by tight waistbands, belts, or clothing pressing on the outer hip

How to distinguish meralgia paraesthetica from sciatica

True sciatica from a spinal nerve root follows a dermatomal pattern — it typically extends from the back through the buttock and down the back or outer calf to the foot. Meralgia paraesthetica stays on the outer thigh only and does not reach below the knee. There is usually no back pain. This distinction can be made from symptoms alone in most cases.

Common causes and risk factors

Obesity — increased abdominal girth increases compression at the inguinal ligament
Pregnancy — increased abdominal size and altered pelvic mechanics
Tight clothing, belts, or waistbands — direct external compression of the nerve
Prolonged sitting or desk work — hip flexion position compresses the nerve at the groin
Diabetes — neuropathy increases vulnerability to peripheral nerve compression
Recent weight gain — sudden increase in abdominal load

What helps?

Address contributing factors

Loose clothing, weight management where relevant, workstation adjustment, and avoiding prolonged hip flexion are often sufficient for mild cases. Many people improve significantly with these measures alone within weeks.

Manual therapy

Soft tissue release of the inguinal area and hip flexors, and neural mobilisation techniques for the LFCN. An osteopath or physiotherapist experienced in nerve entrapments can assess and treat the specific point of compression.

Local injection

An injection of local anaesthetic and steroid near the LFCN at the inguinal ligament is highly effective for persistent cases. Often provides lasting relief and can be both diagnostic and therapeutic.

Surgery

Rarely required. Surgical decompression or nerve transection for severe, refractory cases that have not responded to conservative management and injection.
