FREQUENTLY ASKED QUESTIONS — NERVE BLOCK TREATMENT DELHI NCR

Q1. What is a nerve block?

A nerve block is an injection of local anaesthetic (and sometimes steroid) near a specific nerve or group of nerves to interrupt pain signals. It provides targeted relief for chronic pain conditions, precise diagnosis, and can have long-lasting effects.

Q2. What conditions can nerve blocks treat?

Nerve blocks treat sciatica, facet joint pain, occipital neuralgia, trigeminal neuralgia, cancer pain, complex regional pain syndrome (CRPS), post-herpetic neuralgia, and pain after surgery or injury.

Q3. What types of nerve blocks does Eshna offer?

We offer epidural nerve blocks, selective nerve root blocks, facet joint medial branch blocks, occipital nerve blocks, sympathetic nerve blocks (stellate ganglion, coeliac plexus, lumbar sympathetics), and peripheral nerve blocks.

Q4. How does a nerve block work?

Local anaesthetic blocks sodium channels in nerve cell membranes, preventing electrical signals from travelling along the nerve. This interrupts pain transmission from the affected area to the brain, providing relief.

Q5. Is a nerve block the same as an epidural?

An epidural is a specific type of nerve block where medication is injected into the epidural space of the spine, affecting multiple nerve roots. Other nerve blocks target individual nerves or specific nerve clusters.

Q6. How long does a nerve block last?

Local anaesthetic nerve blocks last hours to days. When combined with steroid, effects can last weeks to months. For diagnostic purposes, a short-acting block helps confirm the pain source before planning longer-term treatment.

Q7. Can nerve blocks be used to diagnose pain sources?

Yes. Diagnostic nerve blocks are a key tool in pain medicine. If pain resolves with a targeted block, this confirms the blocked nerve is the pain source and guides further treatment (such as radiofrequency ablation).

Q8. What is a sympathetic nerve block?

Sympathetic nerve blocks target the sympathetic nervous system — chains of nerves that contribute to pain from CRPS, vascular conditions, and certain visceral cancers. The coeliac plexus block for abdominal cancer pain is one example.

Q9. What is a stellate ganglion block?

A stellate ganglion block injects local anaesthetic near the stellate ganglion (sympathetic nerve cluster in the neck). It treats CRPS of the upper limb, facial pain, and certain vascular conditions of the arm and hand.

Q10. Are nerve blocks safe?

Yes. When performed by experienced interventional pain specialists under imaging guidance (fluoroscopy or ultrasound), nerve blocks are very safe procedures with well-established efficacy and low complication rates.

Q11. What is the difference between a nerve block and radiofrequency ablation?

A nerve block provides temporary pain relief by numbing the nerve. Radiofrequency ablation (RFA) uses heat to permanently deactivate the nerve, providing much longer-lasting relief (months to years).

Q12. How many nerve block injections will I need?

This depends on the condition and response. A single block may provide lasting relief. Some conditions benefit from a series of 3 blocks. Diagnostic blocks are typically followed by a longer-term treatment.

Q13. Can nerve blocks help cancer pain?

Yes. Specific nerve blocks are highly effective for cancer pain. A coeliac plexus block dramatically reduces pain from pancreatic and upper abdominal cancers. Superior hypogastric plexus block treats pelvic cancer pain.

Q14. What should I expect during and after a nerve block procedure?

The procedure takes 15–30 minutes. You may feel pressure or brief discomfort during the injection. After, the treated area may feel warm or numb temporarily. Most patients can go home the same day.
