Lateral Femoral Cutaneous Nerve Blocks
Your body has many nerves that can be injured with trauma from friction, pressure, tearing, chemical or natural toxins, radiation therapy or surgery. Neuralgia is a pain caused by an injured or malfunctioning nerve.
The lateral femoral cutaneous nerve is a nerve that receives sensation from the top lateral part of your thighs on each side. When it is dysfunctional because of pressure, injury or entrapment, pain can be felt in the lateral thighs. You also may have tenderness in your groin because it is one location through which the nerve travels. Symptoms you may have include tingling, numbness, or painful stinging sensations in the front or outer parts of your thighs. The area that is painful may also be very sensitive to touch.
A lateral femoral cutaneous nerve block is an injection of local anesthetic and steroid into the area where the nerve travels.
Generally, relief may be obtained within two days to two weeks. If you get good, lasting benefit from the injection, the block may be repeated. In some cases, one injection is all you will need.
