A nerve block is an anti-inflammatory injection targeted toward a certain nerve or group of nerves to treat pain. The purpose of the injection is to "turn off" a pain signal coming from a specific location in the body or to decrease inflammation in that area. Imaging guidance may be used to help the doctor place the needle in exactly the right location so that the patient can receive maximum benefit from the injection.
Preparing for a Nerve Root Block Exam
Typically no advance preparation is required for a nerve root block exam; however, some exams require that you wear a gown during the procedure. You will probably be asked to use the bathroom before the procedure beings.
What to Expect During a Nerve Root Block Exam
Nerve blocks usually take only minutes to administer. The injection will be administered with a syringe much like one that would be used for a routine vaccination. You will be positioned on a table or other surface to allow the doctor access to the site (s) to be injected. The doctor will then identify the spot the needle needs to be placed, using imaging guidance. He or she will clean the area with antiseptic solution, and then the needle will be inserted at a specific depth to deliver the medication as close to the problematic nerve(s) as possible.
After the injection, you will probably experience a sensation of pain relief in the area injected. You will be allowed to rest for 15 to 30 minutes to let the medication take effect. The nurse will also make sure you don't have any unexpected side effects and then you are free to leave the doctor's office.
A radiologist will review your exam images and report the findings to your doctor within 24 hours. Your doctor will then discuss the findings and next steps with you.
