Lateral femoral cutaneous nerve blocks are a minimally invasive, non-surgical treatment for chronic pain. These nerve blocks can help in the diagnosis of chronic hip/thigh pain. In addition, this pain management technique can also provide therapeutic relief by reducing pain signals originating from these nerves. If lasting benefit from the injection is acquired, the block may be repeated intermittently for therapeutic benefit. In some cases, one injection is all you will need.
A lateral femoral cutaneous nerve block is performed either with the assistance of landmarks that can be easily felt by touch (palpation), or under imaging guidance (a live x-ray or ultrasound machine) to increase the accuracy of this procedure.
This procedure is safe. With any procedure, however, there are risks, side effects and possibility of complications. The most common side effect is temporary pain at the injection site. Other less common risks include bleeding, infection, or injection into blood vessels. Serious complications are uncommon. The use of ultrasound or x-ray guidance to provide visualization of the targeted structures significantly minimizes the risks.
