Meralgia Paresthetica

What is Meralgia Paresthetica?

Meralgia paraesthetica, stemming from the compression of the lateral femoral cutaneous nerve, presents a distinctive set of symptoms localised to the outer thigh region. This nerve, responsible solely for sensory functions, can become compressed as it traverses beneath the inguinal ligament, leading to meralgia paresthetica.

The lateral femoral cutaneous nerve is a pure sensory nerve that is vulnerable to compression. The hallmark symptoms of this condition include tingling, numbness, or a burning sensation specifically concentrated over the lateral aspect of the thigh. Patients may describe sensations akin to pins and needles or electric shocks, which can be intermittent or persistent depending on the severity of nerve compression.

Various factors contribute to the development of meralgia paresthetica. Prolonged periods of sitting, particularly on hard surfaces, can exacerbate nerve compression, as can the wearing of tight clothing that places undue pressure on the inguinal region. Additionally, habits such as frequently carrying objects like keys in the front pockets, where they press against the inguinal area, can contribute to nerve irritation. Obesity is another common predisposing factor, as excess adipose tissue can increase pressure on the nerve as it passes through the inguinal region.

The diagnosis of meralgia paraesthetica typically involves a thorough medical history and physical examination to identify characteristic symptoms and potential contributing factors. In some cases, diagnostic tests such as nerve conduction studies or imaging studies like ultrasound or MRI may be employed to confirm the diagnosis and assess the extent of nerve compression.

Management of meralgia paresthetica often begins with conservative measures aimed at alleviating symptoms and addressing underlying causes. This may include lifestyle modifications such as avoiding prolonged sitting, wearing looser clothing, and refraining from carrying heavy objects in pockets. In cases where conservative measures fail to provide relief, medical interventions such as nerve blocks or surgical decompression of the affected nerve may be considered to alleviate symptoms and improve overall quality of life.
