Interventional nerve blocks are targeted nerve block injections used to help manage pain by reducing inflammation and interrupting pain signals along specific nerves.
Nerves travel from the spine to many areas throughout the body. When a nerve becomes irritated or compressed, it can cause sharp, burning, or radiating pain. Symptoms may affect the neck, back, arms, legs, or hips, depending on the nerve involved.
At Jacobs Pain Centre in Markham near Toronto, nerve block injections may be used to help treat a variety of nerve-related pain conditions.
A nerve block is a minimally invasive, non-surgical procedure used to help relieve pain. The injection delivers medication around the affected nerve to help calm irritation and reduce pain.
The medication typically includes a local anesthetic and may also include a corticosteroid to reduce inflammation.
By delivering medication directly to the affected nerve, nerve blocks can help:
For many people, nerve blocks are used as part of a broader pain management plan.
Interventional nerve block injections may be considered for people experiencing:
Treatment recommendations are based on clinical assessment and symptom patterns.
Depending on the location of symptoms, different types of nerve blocks may be recommended.
Examples performed at Jacobs Pain Centre include:
The type of injection recommended depends on where the pain originates and which nerve is involved.
At Jacobs Pain Centre, nerve block injections may be performed using ultrasound guidance.
Ultrasound imaging allows the physician to visualize nerves, blood vessels, and surrounding tissues in real time, helping guide the needle precisely to the targeted area.
Using ultrasound guidance can help:
Ultrasound-guided nerve blocks are commonly used in the treatment of nerve-related pain and certain headache conditions, including occipital nerve blocks.
Nerve blocks are performed in the clinic setting.
The skin is cleaned and a small needle is guided to the targeted area. Ultrasound guidance may be used when appropriate to support accurate needle placement.
The procedure is typically brief and well tolerated.
Some people may experience temporary numbness in the treated area following the injection.
Pain relief may occur shortly after treatment due to the anesthetic component of the injection.
As inflammation decreases around the nerve, longer-lasting pain relief may develop over the following days.
For many people, relief may last several weeks to several months, depending on the condition being treated.
Reducing pain can also help patients:
If symptoms return, repeat treatment may be considered depending on the individual situation.
Interventional nerve block injections are recommended following a detailed medical assessment, including review of symptoms and physical examination.
The goal is to identify the specific nerve contributing to pain and incorporate treatment into an overall pain management plan tailored to the patient.
Many nerve block injections are performed using ultrasound guidance, which allows the physician to visualize nerves and surrounding structures during the procedure.
The injection procedure is typically brief and performed in the clinic.
Pain relief varies depending on the condition being treated. For some people, relief may last weeks or months.
Most patients tolerate the procedure well. A local anesthetic is used to help reduce discomfort during the injection.
If you are experiencing ongoing nerve-related pain, interventional nerve block injections may be one option to help manage symptoms.
