Spine Center > Nerve Root Block

What is a nerve root block and how is it performed?
A nerve block is performed to determine if a specific spinal nerve root is the source of pain, and to reduce inflammation around the nerve root;thus decreasing or relieving the pain.

Using a CT scan, the radiologist locates a specific spinal nerve root. A needle is introduced through the skin into the area adjacent to the nerve root. Medication is then injected into the area, bathing the nerve root. The medication includes an anesthetic and steroid.

Before the Procedure:
You will be contacted by one of our patient coordinators and will be asked to provide information regarding your current demographics, past medical history, and medications. She will provide you with detailed instructions on how to prepare for the upcoming procedure. You will be asked to hold any blood thinning medications such as Coumadin, Plavix, Aspirin, and any NSAIDS. Any insurance questions can be answered by your referring physician.

The Day of the Procedure:
We ask that you refrain from eating 4 hours prior to your appointment. You must bring your most recent MRI or CT film/CD with you. We do not dispense or provide prescriptions for medications. You will need someone to drive you home. Patients without a driver will be rescheduled for another day.

Following the injection, you may have temporary numbness or weakness of your extremities lasting up to 6 hours. Sometimes it may be difficult to walk due to a lack of sensation in your foot. As this subsides, some patients report increased discomfort. This can be related to irritation from the steroid and will resolve. You should begin to notice progressive pain relief after 10-14 days. We cannot predict or guarantee how much pain relief you will receive. The expected success rate depends on your diagnosis.

How soon can I return to my normal activities after a nerve root block?
Upon discharge, you will be asked to rest for 24 hours and refrain from driving or operating machinery for 24 hours.

Is a nerve root block covered by insurance?
You should direct any insurance questions to your referring physician and/or insurance
