Nerve Injections


Nerve injections may be used as a diagnostic tool and a pain treatment. A nerve block injection

involves the use of an anesthetic to numb a specific nerve or bundle of nerves. They

are used to determine if the nerve or nerve bundle is the actual source of the pain. If a patient

receives the nerve injection and feels no relief in pain, the nerve is determined to not be the

source of the pain.

There are many different types of nerve injections used to both diagnose and treat patients.

Selective nerve root injections are injections of a small amount of anesthetics into a specific

nerve root of the spinal cord. This may be done in the neck, chest, and low back area to both

diagnose and treat pain. Radial nerve injections need only a small amount of anesthetic and may

be done using ultrasound guidance or anatomically. During this procedure the patient is laying

on their back with the arm out and wrist palm side up. Femoral nerve injections are guided by

either ultrasound or nerve stimulation, the quadriceps muscle twitches if the femoral nerve is

stimulated. Femoral nerve injections may be single-shot injections or, for more permanent relief,

a perineural catheter femoral block, both procedures are the same.

Sympathetic Injections


Sympathetic injections are used to treat and diagnose sympathetic pain. The

sympathetic nervous system is a relationship of nerves throughout the entire body originating

from the spine. This collection of nerves effects many bodily functions such as blood pressure

and urination. There are two main ganglions, bundles of nerves, associated with the sympathetic

nervous system. The stellate ganglion is responsible for the upper body while the sympathetic

ganglion is associated with the lower body. Irritation and damage to the ganglion may result in

pain such as headaches and neck pain. During the procedure, the patient is giving a local

anesthetic around the area where the needle will be inserted. X-ray guidance is used to guide the

needle to the ganglion where an anesthetic is injected.
