What is it?
A diagnostic peripheral nerve block is a simple procedure used to find out if a specific nerve is the source of your pain.
How does it work?
Dr. Norton uses ultrasound or X-ray +/- nerve stimulation to locate the nerve
He cleans and numbs the skin, then guides and positions a needle tip adjacent to the nerve
He injects numbing medication around the nerve and removes the needle
If your pain improves after the injection, it tells us that this nerve is likely the cause of your discomfort
Why is it helpful?
✅ Helps identify the exact source of pain
✅ Guides Dr. Norton in choosing the best long-term treatment for you, such as cryoneurolysis or other therapies
✅ Provides temporary relief, giving you an idea of what longer-lasting treatments may feel like
What should I expect?
The procedure is usually quick and done in the office
You may feel pressure or a brief sting from the injection
Relief may last only a few hours, since the medicine is short-acting
It’s generally safe, with low risk of side effects
