Thigh Nerve Issue (Meralgia Paresthetica)

What is meralgia paresthetica?

Meralgia paresthetica is a nerve condition that causes an area of skin over the upper outer thigh to feel numb, tingly, or painful. It is caused by compression of a nerve in the thigh known as the lateral cutaneous nerve. It is typically compressed as it passes underneath a tough fibrous ligament called the inguinal ligament.

Rarity: Rare

Symptoms

• Pain in the outside of the hip
• Pain in one thigh
• Thigh numbness
• Tingling upper leg
• Hip numbness

Diagnosis

To accurately diagnose meralgia paresthetica, your doctor may recommend several diagnostic tests. One common test is a nerve conduction study, which assesses the flow of electrical current through the lateral femoral cutaneous nerve. This test can help determine if the nerve is functioning properly or if there is compression or damage. During a nerve conduction study, electrodes are placed on the skin to measure how quickly electrical signals travel through the nerve.

In some cases, imaging tests such as a CT scan may be ordered to rule out other potential causes of thigh pain. A CT scan can provide detailed images of the pelvis and surrounding structures, helping to identify any masses or abnormalities that might be compressing the nerve. While not always necessary, these diagnostic tests can be valuable tools in confirming a diagnosis of meralgia paresthetica and ruling out other conditions with similar symptoms.

Treatment

You should see a doctor to confirm the diagnosis and discuss treatment options. Generally, this condition is treated with rest, physical therapy, pain medication, and occasionally corticosteroid injections.
