Why was this Procedure Performed?

This procedure is often done to help find the cause of your hip and leg pain and also can assist in the treatment of the pain. These nerves travel from your back to your legs. Pressure or irritation of these nerves will result in hip pain, leg pain or both. The most common reason this might occur is with a herniated disc. By using local anesthetic and “turning off" the nerve, we can have some idea as to the cause of your pain. In addition, by placing a small amount of steroid onto the nerve root we can help relieve the inflammation and swelling of the nerve. This will usually result in improved pain relief.

How is the Procedure Performed?

You may have an intravenous line (IV) inserted before the procedure. A small needle will be inserted in your lower or middle back near the spine. The needle will always be inserted under X-ray guidance as this helps guide the needle to the exact location. When the needle is in the correct position, local anesthetic and steroid will be injected to temporarily 'turn off' the nerve and decrease the inflammation. After the procedure, you will be watched in the recovery area.

What can you expect after the Procedure?

After the procedure is performed, you may notice some numbness or tingling in the hip or legs. Rarely, your hips or legs may also be weak and difficult to control. These symptoms are due to the local anesthetic and usually resolve in a few hours. It may take up to 24-36 hours until the steroid begins to help the inflammation and pain. Therefore you may notice a return of your pain between the time that the local anesthetic wears off and the steroid takes effect. You will be asked to keep a detailed pain diary to help you keep track of the level of pain you experience after the procedure. You and the doctor will discuss this at your next visit.

You will need someone to drive you home, as your ability to drive may be impaired. You should also avoid any unassisted walking, climbing or activities that require the use of your arms until the numbness and weakness wears off.

What if you have worrisome side effects or other concerns?

You may experience a small amount of bruising, bleeding or swelling at the injection site. It is best to apply ice compresses in the first 24 hours followed by heat after 24 hours short durations (usually 20 minutes at a time). Please continue your regular medications. If you are experiencing other difficulties or side effects, please call the office at 502-PAIN (7246) so that we may recommend further action or please go to the nearest emergency room for evaluation.
