Nerve block injections provide temporary pain relief to different parts of the body. The injection blocks the pain signal being sent from the injured part of the body using anti-inflammatory or pain reducing medication. The goal is to reduce the pain and/or inflammation.
Types of Nerve Block Injections
Since nerve block injections can be used on different parts of the body, there are several different types of injections you may receive. Some of the most common types of nerve block injections are:
- Lumbar epidural injections
- Celiac plexus nerve block injection and Subarachnoid nerve block injections
- Stellate ganglion nerve block injection
- Facet joint nerve block injection
- Cervical paravertebral nerve block injection and Cervical plexus nerve block injection
- Sympathetic nerve block injection
Nerve Block Injection Procedure
A Nerve block injection is a simple outpatient procedure that can be done in just a few minutes. It does not require sedation, but you will be given a local anesthetic to ease your discomfort. Your physician may use a fluoroscope to guide the needle into the injection point.
After the procedure has been completed, you should be able to walk around normally, but it’s recommended that you bring someone with you to drive back. The area you were injected at may be sore afterwards. You can take pain relief medicine or put ice on it.
How long do Nerve Block Injections last?
Nerve block injections usually take effect almost immediately after the procedure. But you should remember that this is not a permanent solution for your pain. The injection will last for up to two weeks in most cases. After all the medication has been absorbed by the affected area, the pain will likely come back. Some patients have experienced long term pain relief after several nerve block injections however.
