Nerve Block
A non-surgical spinal procedure performed under a C-arm (real-time imaging) that delivers medication just outside the dura, the membrane surrounding the spinal nerves.
Medication is placed directly at the damaged part of the lower back or neck through a fine needle. It calms inflammation and swelling around the nerve and restores the normal response of the autonomic nervous system.
Recommended for
- Numbness and lower back pain from the spine
- Pain after spine surgery or a traffic accident
- Pain that does not respond to medication or physical therapy
- Chronic pain with no clear cause
Useful for diagnosing spinal pain with complex causes, and relief is immediate.
Symptoms can recur later.
Questions patients ask
How is a nerve block done?
We locate the lesion with an image intensifier (C-arm). We then address the source of pain, widen the nerve canal where the nerve is compressed, and inject an anti-adhesion agent. Nerve swelling and inflammation settle and adhesions around the nerve are released so it can move freely.
Who should not have a nerve block?
Tell your doctor in advance if you have a bleeding disorder, take anticoagulants such as warfarin, or have a severe allergy to injections.
How should I care for myself afterward?
A light shower is fine on the day, but avoid saunas, and avoid strenuous movement for 3 to 4 days. Temporary partial weakness can occur but usually resolves within 1 to 2 hours. Come with a companion on the day and do not drive.
AftercareRest in bed for at least 30 minutes afterward while we watch for drug reactions and motor weakness. If nothing unusual appears, you can go home.
