Meralgia paresthetica is a neurological condition caused by the compression of the lateral femoral cutaneous nerve, leading to pain, numbness, and paresthesia in the outer thigh.
1.1 Definition and Overview
Meralgia paresthetica (MP), also known as Bernhardt-Roth syndrome, is a neurological condition characterized by the compression of the lateral femoral cutaneous nerve (LFCN). This results in sensory disturbances, such as pain, numbness, and paresthesia, primarily affecting the outer thigh. The term “meralgia” originates from the Greek words “meros” (thigh) and “algos” (pain). MP is often described as a burning, tingling, or itching sensation in the affected area. It is not caused by damage to the thigh itself but rather by nerve entrapment, making it a compressive mononeuropathy. Accurate diagnosis and management are crucial for symptom relief and improving quality of life.
1.2 Importance of Patient Education
Patient education is crucial in managing meralgia paresthetica, as it empowers individuals to understand their condition and actively participate in their care. Educating patients about symptoms, causes, and treatment options fosters better decision-making and adherence to therapy. It also encourages lifestyle modifications, such as weight management and activity adjustments, which are vital for symptom relief. Additionally, patient education addresses emotional and psychological aspects of chronic pain, reducing anxiety and improving overall well-being. Informing patients about when to seek medical help and how to monitor progress ensures timely interventions and prevents complications, making it a cornerstone of effective management.
Clinical Characteristics of Meralgia Paresthetica
Meralgia paresthetica is characterized by burning, tingling, or numbness in the outer thigh due to nerve compression, often without visible muscle weakness or reflex changes.
2.1 Symptoms and Presentation
Meralgia paresthetica typically presents with burning, tingling, or numbness in the outer thigh. Patients often describe a pins-and-needles sensation or discomfort that worsens with prolonged standing or walking. The symptoms are usually unilateral, affecting one side of the body, and may radiate across the anterolateral thigh. Some individuals report heightened sensitivity to light touch or clothing. These sensations can vary in intensity, ranging from mild discomfort to severe pain, and may worsen at night or with specific activities like tight clothing or prolonged sitting. The condition does not typically cause muscle weakness or reflex changes, focusing primarily on sensory disturbances.
2.2 Paresthesia and Pain Description
Meralgia paresthetica is characterized by paresthesia, often described as a burning, tingling, or itching sensation in the outer thigh. Pain can range from mild discomfort to severe, sharp, or stabbing sensations.

Causes and Risk Factors
Meralgia paresthetica is primarily caused by compression of the lateral femoral cutaneous nerve, often due to tight clothing, obesity, or poor posture. Pregnancy and diabetes are also risk factors.
3.1 Nerve Compression and Pathophysiology
Meralgia paresthetica occurs when the lateral femoral cutaneous nerve (LFCN) is compressed, disrupting normal nerve function. This compression often happens near the inguinal ligament or within tight fascial compartments. The LFCN, responsible for sensation in the anterolateral thigh, becomes irritated, leading to abnormal nerve signaling. Prolonged compression can cause demyelination and axonal damage, resulting in pain, paresthesia, and sensory loss. The condition is exacerbated by factors like obesity, tight clothing, or repetitive hip flexion, which increase pressure on the nerve. Understanding this pathophysiology is key to effective diagnosis and treatment.
3.2 Contributing Factors and Triggers
Several factors contribute to the development of meralgia paresthetica, including obesity, tight clothing, and prolonged standing. Repetitive hip flexion, common in activities like cycling or hiking, can also trigger symptoms. Pregnancy, diabetes, and leg length discrepancies may increase susceptibility. External compression from belts or wallets can exacerbate nerve irritation. Understanding these triggers helps patients avoid aggravating activities and adopt preventive measures to reduce discomfort and manage the condition effectively.
