Overview
Meralgia paresthetica occurs when the lateral femoral cutaneous nerve becomes compressed as it passes under the inguinal ligament near the front of the hip bone, on its way to supply skin over the outer thigh.
Because this nerve is purely sensory, meralgia paresthetica changes sensation only — it never causes leg weakness. Weakness alongside thigh symptoms points to a different or additional cause and should be assessed.
Common Symptoms
- Burning, tingling or numbness limited to the outer thigh
- Symptoms that build with standing or walking and ease with sitting
- Discomfort near the front of the hip, sometimes with a specific tender spot below the hip bone
- No weakness of the leg — because this nerve carries sensation only, not motor signals
Low back problems and hip joint conditions can also produce thigh symptoms, so a clear sensory-only pattern over the outer thigh — without back pain, leg weakness or joint stiffness — is a useful clue that this nerve is involved.
Practical Changes
Many cases improve with removing the source of compression: loosening tight belts, waistbands or duty gear, and addressing weight gain or a change in activity level where relevant. Reducing prolonged standing or hip-extended postures that stretch the nerve against the ligament can also help.
Persistent symptoms are usually assessed clinically; imaging or nerve studies are sometimes used when the diagnosis is unclear or symptoms don't settle with simple changes.
When to Get It Assessed
Arrange assessment for symptoms that persist beyond a few weeks despite reducing compression, symptoms that spread or worsen, or any accompanying leg weakness, back pain or other neurological symptoms — these suggest a cause beyond this nerve alone.
