Chemical neurolysis uses agents such as alcohol or phenol.
What Is Neurolysis?
Neurolysis is a targeted procedure that deliberately disrupts a confirmed pain-carrying nerve pathway using a chemical agent, controlled radiofrequency heat, or extreme cold, to produce relief that outlasts any temporary injection. At Nivaan, it's considered only after the pain source has been carefully assessed and, in most cases, confirmed with a diagnostic block first.
It's worth being precise about what falls under this term. Neurolytic blocks (chemical destruction using alcohol or phenol) are best established for selected cancer-related visceral pain. Radiofrequency neurolysis, sometimes called radiofrequency ablation, uses controlled heat and is the technique most commonly applied to confirmed facet-joint pain and selected peripheral nerve conditions. Cryoneurolysis uses extreme cold, leaving the nerve sheath intact so regeneration is more predictable. None of these is a generic treatment for chronic pain, each is matched to a specific nerve, a specific diagnosis, and a specific clinical situation.
How Does Neurolysis Work?
A neurolytic procedure deliberately reduces the ability of selected sensory nerve fibres to transmit pain.
Radiofrequency neurolysis creates a controlled thermal lesion.
Cryoneurolysis uses carefully controlled cold.
Because nearby nerves may also control movement, sensation, or organ function, target selection and image-guided placement are essential. A temporary local-anaesthetic block is often used first to predict benefit and identify unwanted effects before a longer-lasting procedure is considered.
Conditions Considered for Neurolysis in Mumbai
Neurolysis isn't broadly applicable, it's reserved for specific pain conditions where a defined nerve or plexus can be targeted and the evidence supports intervention:
Cancer-related visceral pain is the most clinically established use. Coeliac plexus neurolysis for pancreatic and upper abdominal cancer pain, and hypogastric plexus blocks for pelvic cancer pain, have the longest track record and the strongest evidence. The aim is meaningful pain reduction and lower medication burden as part of palliative care, not a cure, but a genuine improvement in daily comfort.
Confirmed facet-joint pain in the neck or lower back is the other well-supported indication specifically radiofrequency neurolysis after a diagnostic medial-branch block has clearly demonstrated relief at the same target.
Selected pelvic, perineal, or peripheral nerve pain may be considered where the diagnosis is clear, the nerve is targetable, and the evidence supports intervention for that specific condition. Your specialist will be direct about what the evidence does and doesn't support in your case.
Who Is a Suitable Candidate for Neurolysis Treatment?
Neurolysis may be considered when:
Pain remains disabling despite appropriate medication and conservative treatment
The pain can be linked to a specific nerve, branch, ganglion, or plexus
A temporary diagnostic block provided meaningful relief with no unacceptable functional loss
You understand that relief may be temporary, and treatment doesn't cure the underlying disease
Neurolysis is generally avoided when the target is uncertain, infection or uncontrolled bleeding risk is present, or loss of the nerve's other functions could cause unacceptable harm.

The Neurolysis Procedure, Step by Step
Before the procedure:
- Review of diagnosis, imaging, medications, allergies, and bleeding risk
- Confirming response to a diagnostic block where clinically required
- Pausing blood-thinning medicines, only on explicit medical advice
- A discussion of expected sensory change, duration, alternatives, and target-specific risks
- Arranging transport if sedation is planned
What happens during treatment:
- STEP 1Positioning - you're positioned so the target nerve or plexus can be reached safely.
- STEP 2Sterile preparation - the skin is cleaned and local anaesthetic used for comfort.
- STEP 3Image-guided placement - a fine needle or probe is advanced under fluoroscopy or ultrasound.
- STEP 4Safety confirmation - contrast, stimulation testing, or a test dose may confirm position before treatment.
- STEP 5Neurolysis - the selected chemical, thermal, or cold technique is applied to the confirmed target.
- STEP 6Observation - strength, sensation, pain response, and vital signs are checked before discharge.
Recovery and Aftercare
Temporary soreness, numbness, or a short pain flare can occur; target-specific instructions take priority since recovery differs between plexus, spinal, and peripheral procedures.
| Time | What to Expect |
|---|---|
| Immediately after | Observation of pain response, strength, sensation, and vital signs |
| First 24-48 hours | Injection-site soreness or temporary numbness may occur |
| Days 3-14 | The treatment effect becomes clearer as procedural irritation settles |
| Following months | Relief is reviewed; nerves may recover and symptoms can return |
Rehabilitation, medication, cancer care, or other treatment continues according to the underlying diagnosis.
Benefits, Risks, and Side Effects
Benefits
Targeted - treats a confirmed pain pathway rather than exposing the whole body to more medication
Longer relief - can last longer than a temporary local-anaesthetic nerve block
Medication reduction - may reduce reliance on systemic analgesics in appropriate patients
Functional support - pain reduction can support movement, sleep, rehabilitation, or palliative goals
Risks and Side Effects
Neurolysis intentionally alters nerve function, so its risks are discussed more carefully than those of a temporary nerve block:
Pain flare or neuritis - burning, tingling, or increased pain as the treated nerve responds
Numbness or weakness - unwanted sensory or motor change if nearby fibres are affected
Bleeding or infection - uncommon procedural risks, reduced by screening and sterile technique
Adjacent-structure injury - target-specific nerve, vessel, organ, or spinal injury, uncommon but potentially serious
Incomplete or temporary relief - pain may improve only partially or return as nerves regenerate or disease progresses
The balance of benefit and harm depends strongly on diagnosis, target, technique, and your overall health.
Results and Duration of Neurolysis
Results vary widely by nerve target, technique, and underlying condition.
Early response - relief may begin after procedural soreness settles.
Following weeks - function, medication use, sleep, and pain are reviewed together.
Several months - many neurolytic blocks are intended to provide relief over months, not a permanent cure.
Structured review - further treatment is based on response and the course of the underlying condition.
For cancer-related neurolytic blocks, the aim is often meaningful pain and medication reduction as part of palliative care. For radiofrequency neurolysis, a positive diagnostic block is an important predictor but doesn't guarantee outcome.
Neurolysis Cost Considerations in Mumbai
Cost varies significantly by the nerve or plexus targeted, the technique used (chemical, radiofrequency, or cryoneurolysis), and whether a prior diagnostic block is required. For cancer-related neurolysis specifically, this is often considered alongside broader oncology treatment costs, worth discussing with your care team as part of your overall treatment planning, not as an isolated expense.
Why Choose Nivaan Care for Neurolysis in Mumbai?
Neurolysis at Nivaan is considered within a complete specialist-led plan, with diagnostic confirmation, transparent risk discussion, and ongoing multidisciplinary support, an interventional pain specialist confirms the exact diagnosis, a physiotherapist builds a personalised rehabilitation plan, and a pain counsellor supports the fear and stress that accompany persistent pain.
Frequently Asked Questions
No. A diagnostic nerve block uses local anaesthetic and is temporary. Neurolysis is considered only after the pain source has been carefully confirmed, and is intended to produce longer relief by disrupting the selected pain pathway.
Neurolytic blocks are most established for carefully selected cancer-related visceral pain. Radiofrequency neurolysis may also be used for confirmed facet-joint or selected peripheral nerve pain.
It varies by technique, nerve target, and underlying condition, often several months. Nerves can regenerate, and pain may return; your specialist will explain realistic expectations for your specific diagnosis.
Not necessarily. Although it intentionally disrupts a pain pathway, nerve fibres can regenerate and the underlying disease may progress. Treatment is planned as part of ongoing specialist care, not presented as a guaranteed cure.
Yes, neurolysis is offered as part of Nivaan Care's non-surgical, interventional pain management approach for patients in Mumbai, including for cancer-related pain.
