Learning About a Femoral Nerve Block
What is a femoral nerve block?
A femoral nerve block is a shot of numbing medicine around the femoral nerve. This nerve runs from your lower back all the way down to your hip and leg. The nerve sends movement and feeling signals to and from that part of your body.
The nerve block usually goes into your groin area. It's used to numb the leg and knee for a procedure and to help with pain afterward.
How is a femoral nerve block done?
The doctor may use ultrasound to help guide the nerve block needle.
After finding the right spot, the doctor injects a numbing medicine into the skin near where you will get the nerve block. Then he or she puts the nerve block needle into the numbed area. You may feel some pressure. But you should not feel pain.
What can you expect after a femoral nerve block?
The shot will leave your leg partly or totally numb for a while. Your doctor will tell you how long.
You will need someone to drive you home.
As the block wears off, you will start to feel some pain from the surgery. Be sure to take your pain medicines before the pain gets bad.
Problems from a nerve block are rare. There is a small risk of problems like seizures, heart problems, damage to nerves, infection, or bleeding. The benefits usually outweigh these risks.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
