Spinal injections are highly effective for combating heavy neck and back pain. This one is suitable for the individuals who are not ready to engage in a surgery.
Key Takeaways
- Targeted Inflammation Relief: Injections deposit medication directly into the epidural space or spinal joints, bypassing systemic side effects of oral pain pills.
- Diagnostic vs. Therapeutic: Diagnostic blocks (like Medial Branch Blocks) pinpoint the exact pain source, while therapeutic injections (like Epidurals) provide long-term inflammation reduction.
- Regenerative Options: Platelet-Rich Plasma (PRP) uses your body’s own growth factors as a non-steroidal alternative for tissue repair.
- Image Guidance Is Mandatory: High-precision ultrasound or fluoroscopy ensures millimeter accuracy and patient safety.
Over 8 million people in Canada live with chronic pain, according to official surveillance data from Health Canada. Clinical studies published by Spine-health show that over 70% of patients with sciatica or herniated discs experience significant pain reduction following targeted epidural steroid injections, preventing or delaying surgical intervention.
What are the Different Types of Spinal Injections?
Spinal injections are of varied types. These include:
Epidural Steroid Injections
What They Target: The epidural space surrounding the spinal cord and nerve roots.
How They Work: Delivers a combination of a long-acting corticosteroid and a local anesthetic to wash away inflammatory proteins around irritated spinal nerves.
Delivery Routes: Depending on your anatomy, specialists perform transforaminal (focused on one specific nerve root), interlaminar (covering a wider spinal area), or caudal (lower sacral region) approaches.
Best Used For: Sciatica, herniated or bulging discs, spinal stenosis, and bone spurs.
Duration: Relief typically lasts from several weeks to 3 to 6 months.
Facet Joint Injections
What They Target: The small stabilizing joints (facet joints) located between each set of vertebrae.
How They Work: Injects anti-inflammatory steroids directly into the joint capsule to relieve localized spinal arthritis pain.
Best Used For: Facet joint arthritis, degenerative disc disease, and spinal stiffness when bending backward or twisting.
Duration: Relief lasts from several weeks to several months.
PRP Injections
What They Target: Damaged spinal ligaments, disc tears, and facet joints.
How They Work: Concentrates platelets drawn from your own blood and injects them into the injured site to stimulate your body’s natural tissue repair mechanisms.
Best Used For: Patients seeking a non-steroidal, natural alternative to traditional cortisone.
Medial Branch Nerve Blocks
What They Target: The tiny medial branch nerves that send pain signals from the facet joints to the brain.
How They Work: Injects a precise dose of local anesthetic near the nerve. If your pain drops by 50% to 80% over the next few hours, it confirms the facet joint is the true cause of your pain.
Next Step: A positive block identifies candidates for Radiofrequency Ablation (RFA), a procedure that gently heats the nerve to provide 6 to 18 months of lasting relief.
PS: This is a diagnostic procedure.
Sacroiliac (SI) Joint Injections
What They Target: The SI joints connecting the lower spine (sacrum) to the pelvis.
How They Work: Delivers anti-inflammatory medication directly into the SI joint to relieve lower back, buttock, and groin pain.
Best Used For: Sacroiliitis, pelvic instability, and ankylosing spondylitis.
| Injection Type | Primary Target | Main Purpose | Expected Onset | Typical Relief Duration |
|---|---|---|---|---|
| Epidural Steroid (ESI) | Epidural Space / Nerve Roots | Reduces nerve swelling & sciatica | 2 to 7 days | 1 to 6 months |
| Facet Joint Injection | Vertebral Joint Capsule | Calms joint arthritis & stiffness | 24 to 72 hours | 1 to 3+ months |
| Medial Branch Block | Medial Branch Nerves | Diagnoses exact joint pain source | 15 to 30 minutes | 4 to 24 hours (Diagnostic) |
| Sacroiliac (SI) Block | SI Joint (Pelvis/Spine) | Treats low back & buttock pain | 1 to 3 days | 1 to 4 months |
| Platelet-Rich Plasma (PRP) | Disc Tears / Facet Joints | Stimulates biological tissue repair | 2 to 6 weeks | Long-term / Progressive |

Alternative Options: Intravenous (IV) Ketamine Infusions
For patients dealing with severe, complex chronic pain where traditional treatments have failed, intravenous (IV) Ketamine or FDA-approved Esketamine nasal spray provides a non-surgical option that targets NMDA receptors to reset overactive pain processing pathways in the central nervous system.
For patients dealing with severe, complex chronic pain (such as Complex Regional Pain Syndrome, neuropathic pain, or central sensitization) where traditional treatments have failed, Intravenous (IV) Ketamine Infusions provide a non-surgical alternative. Ketamine blocks NMDA receptors in the central nervous system, helping “reset” overactive pain processing pathways in the brain and spinal cord.
Please note that Ketamine is not a spinal injection for back pain. Unlike epidurals or joint blocks that are injected directly into the spine, Ketamine for chronic refractory pain is administered intravenously into the arm.
If traditional spinal injections or conservative therapies have not provided relief, IV Ketamine can be a highly effective alternative for severe chronic back and neck pain. At Docteur Douleur, intravenous Ketamine is used for patients with refractory spinal pain and central sensitization. Ketamine works by blocking NMDA receptors in the nervous system, helping to reset how your brain and spinal cord process chronic pain signals.
What are the Benefits of Spinal Injections for Pain Relief?
Spinal injections are considered for chronic pain because of several benefits. Like:
Targeted Pain Suppression: Medications delivered through any type of spinal injection goes directly to the joint. This offers relief within a short span.
Rapid Inflammation Reduction: High-dose corticosteroids result in breaking inflammatory chemicals and proteins that lead to nerve irritation. If you consider cortisone injections for back pain relief, this leads to quick reduction of inflammation.
Delaying Surgery: Spinal injections are capable of managing severe chronic pain. This results in delaying or dismissing surgeries.
Identifying the Pain Source: Apart from therapeutic benefits, spinal injections also offer diagnostic benefits. Like, doctors inject local anesthetics into facet joints or a precise nerve root to see immediate responses.
What are the Drawbacks of Spinal Injections for Pain Relief?
Spinal injections come with a range of drawbacks. These include:
Temporary Effects: Spinal injections are anti-inflammatory, and they do not cure the underlying condition. A key limitation is that the effects do not last long.
Osteoporosis Risk: There is a chance of osteoporosis development because of repeated steroid use. This results in brittle bones, and a higher fracture risk.
Varied Patient Response: Spinal injections do not provide uniform relief to everyone. Some patients experience significant pain reduction, while others feel little to no change. Additionally, it is common to experience a brief, short-term increase in localized soreness around the injection site for the first 24 to 48 hours before the anti-inflammatory medication takes full effect.
Are Spinal Injections Right For You?
How to understand whether you are a perfect fit for spinal injections? You are the right candidate if:
- You are dealing with spinal conditions, like herniated disc, facet arthritis, SI joint dysfunction, etc.
- You have tried conservative treatments for several months but the pain sustains
- Your pain is impacting your daily life activities
- You do not have any infection at or near the pain site
- You are not on blood thinners
Well, spinal injections are not recommended for you if:
- You are dealing with an active infection
- You are pregnant (steroid injections are generally avoided during pregnancy)
- You have uncontrolled diabetes
- You have a bleeding disorder
Pro Tip: Spinal injections are most effective when used as part of a comprehensive pain management plan. Reducing acute pain allows patients to participate comfortably in physical therapy and rehabilitation exercises needed for long-term recovery.
What You May Expect During a Spinal Injection Procedure
Here’s how a typical spinal injection for pain relief may look like:
Step 1: Local Skin Numbing
Preparation & Comfort
You lie comfortably face down on a specialized procedure table. The physician cleans the skin over your spine and applies a local anesthetic (lidocaine) to completely numb the entry site.
Step 2: Live Image Guidance (Fluoroscopy)
Precision Mapping
Using live X-ray guidance (fluoroscopy) or ultrasound, the physician views your spinal anatomy in real-time to guide the thin needle safely to the exact target area.
Step 3: Contrast Dye Confirmation
Verification
A tiny drop of contrast dye is injected to confirm that the medication will flow precisely around the target nerve or joint without entering blood vessels.
Step 4: Targeted Injection
Medication Delivery
The therapeutic mixture (corticosteroid, local anesthetic, or PRP) is gently injected. You may feel a brief sensation of pressure in your back or leg.
Step 5: Observation & Discharge
Recovery
The needle is removed and a small bandage is applied. You rest in the recovery area for 15 to 30 minutes while medical staff monitor your vitals before you head home.
What you Should and Shouldn’t Do After Getting Spinal Injections
Given below are some guidelines for getting spinal injections.
| Category | Do This ✅ | Avoid This ❌ |
|---|---|---|
| Pre-Procedure | Arrange for a responsible adult driver to take you home after your appointment. | Don’t eat heavy meals 2 to 4 hours prior if conscious sedation is planned. |
| Post-Procedure | Rest quietly for the first 24 hours and apply ice packs for temporary site soreness. | Don’t soak in a hot tub, bath, or pool for 48 hours to prevent infection. |
| Activity Level | Gradually resume light walking and physical therapy as your pain improves. | Don’t perform heavy lifting, twisting, or strenuous exercise for 72 hours. |
| Medication Usage | Monitor your pain levels in a daily journal to help your specialist evaluate success. | Don’t stop required prescription medications without consulting your physician. |

Frequently Asked Questions
1. Are Spinal Injections Painful?
Spinal injections do not cause significant pain. Rather, most patients experience a bit of pressure or mild discomfort. Local anesthesia is used to numb the skin before the insertion of needles. At Docteur Douleur, physicians use ultrasound guidance to minimize the number of required needle passes.
2. How many Spinal Injections can I have per Year?
This depends on the type of spinal injection administered. Epidural spinal injections are limited to 3 to 4 annually in a given spinal region. Facet joint injections and medial branch blocks are also considered in limited numbers. Regenerative options like PRP are considered for patients who need treatment frequently.
3. Can I Return to Work After a Spinal Injection?
You can return to light work within 24 to 48 hours after a spinal injection. You must avoid strenuous activities for the next 72 hours of an injection. If your work involves high physical activities, you should take rest for 2 to 3 days.
4. How will a steroid injection affect my blood sugar if I have diabetes?
Corticosteroids can cause a temporary spike in blood glucose levels that lasts anywhere from 2 to 7 days after the procedure. If you have diabetes, you should monitor your blood sugar more frequently for the first week following your injection and inform your prescribing doctor if your readings remain unusually high.
5. Do I need to stop taking my blood thinners before the appointment?
Yes, in many cases. Anticoagulants (blood thinners) and anti-inflammatory drugs like aspirin, ibuprofen, or prescription blood thinners increase the risk of bleeding around the spinal cord. Never stop taking prescribed medication on your own—your pain specialist will coordinate directly with your primary care doctor or cardiologist to determine if and when it is safe to temporarily pause your blood thinners before the procedure.
