When it comes to managing chronic or severe pain, two advanced procedures often come into consideration: nerve blocks and neurolysis. Though both target nerves to relieve discomfort, they differ significantly in purpose, technique, and duration of relief. At the Neurology and Pain Management Clinic (NPMC), Dr Gautam Arora helps patients understand these options to choose the most effective treatment plan.

What Is a Nerve Block?

A nerve block involves the injection of an anaesthetic—sometimes combined with a steroid—near a specific nerve or group of nerves. The goal is to temporarily “block” pain signals from reaching the brain.

Nerve blocks are typically used for:

1. Diagnosis: To pinpoint the exact source of pain.
   
2. Short-term pain relief: Useful for acute flare-ups or post-surgical pain.
   
3. Therapeutic relief: In chronic conditions like sciatica, arthritis, or migraines.

Effects can last from a few hours to a few weeks, depending on the medications used and the individual’s response.

What Is Neurolysis?

Neurolysis is a more long-term or semi-permanent solution. It involves the deliberate destruction of nerve fibers to stop pain transmission—either chemically (with alcohol or phenol) or through heat (radiofrequency ablation).

Neurolysis is often recommended for:

1. Cancer pain (e.g., celiac plexus neurolysis for abdominal tumours)
2. Chronic pain that does not respond to conservative treatments
3. Palliative care, where durable pain relief significantly improves quality of life

Since it aims to disable the nerve more permanently, neurolysis is typically performed after diagnostic nerve blocks confirm the right target.

Which One Is Right for You?

Choosing between nerve blocks and neurolysis depends on your pain condition, health status, and how you respond to less invasive options. At NPMC, Dr Gautam Arora uses evidence-based methods to ensure patients receive the safest and most effective treatment.
