Chronic back pain that radiates to the arms or legs can often be traced to irritated or compressed spinal nerves. When medications and physiotherapy do not provide sufficient relief, advanced pain management techniques like Selective Nerve Root Block (SNRB) offer a highly effective, minimally invasive solution.
Dr. Sachin Patil, a leading Consultant Spine Surgeon in Nashik, specializes in advanced spine care procedures, including targeted pain block injections that help diagnose and treat nerve-related pain with precision and safety.
What Is a Selective Nerve Root Block?
A Selective Nerve Root Block (SNRB), also known as a pain block injection, is a minimally invasive procedure where a combination of local anesthetic and anti-inflammatory medication is injected near a specific spinal nerve root.
The goal of this procedure is to:
- Reduce inflammation around the affected nerve
- Provide immediate and long-lasting pain relief
- Identify the exact source of nerve pain (for diagnostic purposes)
This treatment is commonly performed under imaging guidance (fluoroscopy or CT scan) to ensure accuracy.
Who Needs a Nerve Root Block?
Selective nerve root blocks are recommended for patients experiencing persistent nerve pain that has not responded to conservative treatments. You may benefit from this procedure if you have:
- Sciatica (pain radiating down the leg)
- Slip disc (herniated disc)
- Spinal stenosis
- Degenerative spine conditions
- Nerve root inflammation or compression
Consulting Dr. Sachin Patil in Nashik helps determine whether a nerve block is the right option based on your symptoms and diagnostic findings.
Benefits of Selective Nerve Root Block
This procedure offers multiple advantages for patients suffering from chronic spine pain:
- Targeted pain relief: Directly treats the affected nerve
- Minimally invasive: No major surgery or long hospital stay
- Quick procedure: Usually completed within 20–30 minutes
- Faster recovery: Patients can return home the same day
- Diagnostic value: Helps pinpoint the exact pain source
- Reduced need for surgery: In some cases, surgery can be avoided
Procedure Overview The Selective Nerve Root Block procedure is simple and safe when performed by an experienced spine specialist.
Steps Involved:
- Preparation: The patient lies comfortably, and the area is cleaned and numbed with local anesthesia.
- Imaging Guidance: Using fluoroscopy or CT imaging, the needle is carefully guided to the targeted nerve root.
- Injection: A mixture of anesthetic and steroid medication is injected around the nerve.
- Observation: The patient is monitored briefly before discharge.
Most patients experience immediate relief due to the anesthetic, followed by longer-lasting relief as the anti-inflammatory medication takes effect.
Recovery After Pain Block Injection
Recovery is typically quick and uncomplicated. Patients are advised to:
- Rest for the remainder of the day
- Avoid strenuous activity for 24–48 hours
- Resume normal activities gradually
- Follow physiotherapy if recommended
Pain relief may last from weeks to months, depending on the severity of the condition. In some cases, repeat injections may be required for sustained benefit.
When to Consider a Nerve Root Block
You should consider this treatment if:
- Pain persists despite medications and physiotherapy
- You want to avoid or delay spine surgery
- There is confirmed nerve compression on imaging
- Pain significantly affects daily life and mobility
Dr. Sachin Patil, Consultant Spine Surgeon in Nashik, carefully evaluates each case to ensure that nerve block injections are used appropriately and effectively.
