Cervical Nerve Blockage (Treatment of Neck Pain)
Cervical nerve block, also known as a cervical facet joint block or cervical medial branch block, is a procedure used to diagnose and treat neck pain originating from the facet joints or the small nerves that supply these joints in the cervical spine (neck).
The procedure involves injecting a local anesthetic, often combined with a corticosteroid medication, near the affected cervical nerve or nerves to block pain signals and reduce inflammation in the area. It can help determine if the facet joints or their nerve supply are contributing to the neck pain and can provide temporary pain relief.
Here is an overview of the cervical nerve block procedure:
- Pre-procedure evaluation: Before the cervical nerve block, your healthcare professional will review your medical history, conduct a physical examination, and may order imaging tests such as X-rays or MRI scans to identify the potential source of your neck pain.
- Procedure setup: You will be positioned on an examination table, usually lying face down or sitting upright. The injection site(s) will be cleaned and sterilized.
- Local anesthesia: A local anesthetic may be administered to numb the skin and underlying tissues at the injection site. This helps minimize discomfort during the procedure.
- Needle placement and injection: Using fluoroscopy (real-time X-ray guidance), a thin needle is inserted near the affected cervical nerve or nerves. Contrast dye may be used to confirm proper needle placement. Once the needle is in the correct position, the anesthetic and corticosteroid medication are injected.
- Post-procedure observation: After the injection, you may be monitored for a short period to ensure there are no immediate complications. Some healthcare professionals may recommend a short period of rest or observation before allowing you to go home.
The benefits of a cervical nerve block can include:
- Temporary pain relief: The local anesthetic can provide immediate pain relief by blocking pain signals from the affected cervical nerves.
- Diagnostic value: The nerve block can help determine if the facet joints or their nerve supply are the source of your neck pain. If the pain is significantly reduced after the block, it suggests that the facet joints may be contributing to your symptoms.
It’s important to note that a cervical nerve block is typically used as part of a comprehensive treatment plan for neck pain, and its effects are temporary. The duration of pain relief can vary among individuals, lasting from a few hours to several weeks.
As with any medical procedure, cervical nerve blocks carry some risks and potential side effects, such as temporary soreness at the injection site, infection, bleeding, or rare complications related to nerve or spinal cord injury.
If you are experiencing neck pain and are considering a cervical nerve block, it is recommended to consult with a healthcare professional, such as a pain management specialist or anesthesiologist, who can evaluate your condition, determine the appropriateness of the procedure for you, and discuss the potential benefits and risks.
