When is a Spinal Nerve Root Block Injection Recommended?
An injection may be recommended when a single irritated nerve causes pain radiating into the leg or arm. It is particularly useful when pain persists despite physiotherapy and medication. This procedure also confirms the responsible nerve level, which is helpful if surgery is being considered.
Dr. Purnajyoti Banerjee, a consultant orthopaedic spine surgeon, performs these procedures in London with precision under X-ray guidance.
