Medial Branch Block Injection Treatment in London
Home / Services / Injections / Medial Branch Block Injection
A medial branch block injection in London is a diagnostic procedure used to determine whether facet joints are the source of pain in the neck or lower back. Local anaesthetic is placed around the medial branch nerves that carry pain signals from these joints. Temporary pain relief after the injection helps identify the exact structure responsible for symptoms.
It precisely targets the small medial branch nerves that supply the facet joints to uncover whether they are truly causing your pain.
Dr Purnajyoti Banerjee performs the procedure using image guidance to ensure accurate placement and safe delivery.

Targeted Medial Branch Block Injection in London
A medial branch nerve block (also called a facet joint nerve block) involves a local anaesthetic injected near the medial branch nerves.
It delivers short-acting pain relief used for diagnostic purposes and is a diagnostic medial branch block to confirm if facet joints are causing your symptoms. Patients often report neck or lower back pain that is worse with movement or extension.
What To Expect?
You feel genuine hope when pain eases during daily activities.
This pinpoints whether the facet joints are truly responsible.
Dr Purnajyoti Banerjee performs an image-guided injection using X-ray (fluoroscopy) with utmost care.
It may be a lumbar medial branch block or cervical medial branch block, depending on your symptoms.
The procedure is a day-case procedure performed under sterile conditions.
You return home the same day, often with clearer answers.
Who this treatment is designed for

It is particularly appropriate for:
Aching that intensifies with twisting or arching
Stiffness that makes mornings or long sits unbearable
Pain is focused in the spine without radiating further
Frustration after treatments that haven’t helped
Desire for certainty before committing to bigger steps
Temporary pain relief used to guide further treatment brings real peace of mind.

Frequently Asked Questions
What does a medial branch block do?
It temporarily numbs the small nerves to the facet joints. If pain resolves, it confirms that the joints are the source and guides subsequent steps.
How soon is relief felt?
Pain relief often starts within minutes and lasts a few hours to a day. This brief window helps confirm the diagnosis.
Is the injection painful?
The skin is numbed first. Most patients feel only brief pressure or mild discomfort during the quick procedure.
How long does the effect last?
The anaesthetic provides temporary relief (hours to a day). It’s diagnostic, not permanent, but points to effective long-term options.
What happens next if it works?
Positive results often lead to radiofrequency ablation for longer relief. Dr Banerjee discusses the best plan based on your response.
