Understanding Your Options for Back Pain Relief
Back pain injections are minimally invasive procedures that deliver anti-inflammatory medication directly to the source of your pain, offering relief when other treatments haven’t worked. Here’s what you need to know:
Quick Overview:
- What they are: Injections of steroids and/or anesthetics into specific areas of the spine.
- What they treat: Herniated discs, sciatica, spinal stenosis, facet joint arthritis, and other nerve-related back pain.
- How they help: Reduce inflammation around irritated nerves, providing pain relief that lasts for weeks to months.
- Main types: Epidural steroid injections, facet joint blocks, SI joint injections, and trigger point injections.
- Success rate: Studies show at least 50% of patients experience significant pain relief; some injections reduce the need for surgery by up to 54%.
When conservative treatments like over-the-counter medications and physical therapy aren’t enough, back pain injections can offer a path forward. These non-surgical procedures target inflammation and nerve irritation directly at the source, providing meaningful relief that allows you to return to daily activities and improve your quality of life.
The goal isn’t just to mask pain. It’s to reduce inflammation around irritated nerves, giving your body a chance to heal while you work on strengthening and rehabilitation. For many, injections provide months of relief and serve as a bridge to more permanent solutions or a way to avoid surgery altogether.
I’m Dr. Zach Cohen, double board certified in Anesthesiology and Chronic Pain Medicine. I’ve performed thousands of back pain injections using advanced imaging guidance, helping patients throughout San Diego find relief from conditions like herniated discs and spinal stenosis. My approach combines these interventional procedures with comprehensive, customized pain management strategies.

How Injections Work and What They Treat
When you’ve tried over-the-counter medications and physical therapy but the pain persists, back pain injections can make a real difference. Instead of oral medication that affects your whole body, these injections deliver powerful anti-inflammatory medication—usually a corticosteroid—directly to the source of your pain.
Inflammation is often the primary culprit in back pain. When tissues around a nerve become inflamed, they swell and press on the nerve, sending pain signals to your brain. By reducing inflammation at the source, we relieve pressure on the nerve and quiet those signals.
Most back pain injections also include a local anesthetic for immediate relief while the steroid begins to work. The anesthetic wears off in a few hours, but the steroid’s anti-inflammatory effects can last for weeks or months. Injections don’t cure the underlying structural problem, like a herniated disc. Instead, they create a window of opportunity. With less pain, you can effectively participate in physical therapy to strengthen your spine and achieve long-term improvement.
Before any injection, we perform a thorough physical exam and often use imaging studies like an MRI to pinpoint the cause of your pain. Learn more about our back pain diagnosis process.
What Conditions Are Treated with Back Pain Injections?
Different injections target different problems, which is why an accurate diagnosis is crucial.
- Herniated discs: When a disc’s inner material pushes out and presses on a nerve, an injection can reduce the surrounding inflammation, relieving pressure and pain.
- Sciatica: This shooting pain down the leg, also known as lumbar radiculopathy, is caused by compression or inflammation of the sciatic nerve. Epidural steroid injections are particularly effective for this.
- Spinal stenosis: A narrowing of the spinal canal can squeeze nerves, causing pain, tingling, or numbness. Injections reduce inflammation, creating more space for the compressed nerves.
- Facet joint arthritis: Inflammation in the small joints connecting your vertebrae causes localized back pain. Facet joint injections target this specific source.
- Sacroiliac (SI) joint dysfunction: Pain originating from the joints connecting your sacrum and pelvis can be diagnosed and treated with SI joint injections.
- Myofascial pain: Trigger point injections can relax tight, painful muscle knots that cause localized or referred pain.

Diagnostic vs. Therapeutic Injections
Back pain injections can serve as both a diagnostic tool and a treatment.
A diagnostic injection helps us pinpoint the exact source of your pain. We inject a local anesthetic into a suspected nerve or joint. If your pain disappears temporarily, we’ve confirmed the culprit. This precision guides our treatment plan, ensuring we address the actual problem. We often use this approach with diagnostic nerve blocks.
Therapeutic injections are focused on providing lasting pain relief. They typically combine a local anesthetic for immediate comfort with a corticosteroid for long-term anti-inflammatory effects. While they also provide diagnostic information, their main purpose is to reduce pain and improve your quality of life. Often, a single injection can serve both diagnostic and therapeutic purposes, helping us understand and treat the source of your pain simultaneously.
A Guide to the Different Types of Back Pain Injections
There are several types of back pain injections, each designed to target specific structures in your spine. We select the right tool for the job based on the source of your pain. All these procedures are minimally invasive outpatient treatments performed under fluoroscopy (real-time X-ray) guidance. This ensures the medication is delivered precisely and safely for optimal results.

Epidural Steroid Injections (ESI)
ESIs are highly effective for radicular pain—pain that radiates from your back into an arm or leg. This is often caused by conditions like herniated discs or spinal stenosis. The injection delivers a corticosteroid and local anesthetic into the epidural space, a small area surrounding your spinal nerves. This reduces inflammation around the compressed nerve roots, providing relief.
There are three main approaches:
- Transforaminal: The most targeted approach, delivering medication to a specific nerve root as it exits the spine. It is also a powerful diagnostic tool and can help up to 54% of patients avoid surgery.
- Interlaminar: Injected between two vertebrae to reach the epidural space.
- Caudal: Injected through a small opening at the base of the sacrum. Learn more on our Caudal Steroid Injections page.
While not a cure, ESIs provide a window of relief for weeks or months, allowing you to participate in physical therapy. For more details, see our page on the benefits of Epidural Steroid Injection and this medical review.
Facet Joint and Medial Branch Blocks
Facet joints allow your spine to bend and twist, but like other joints, they can become arthritic and painful. This causes axial back pain that may radiate to the buttocks or shoulders.
- Facet joint injections deliver a steroid and anesthetic directly into the inflamed joint to confirm the pain source and provide therapeutic relief.
- Medial branch blocks are primarily diagnostic. We numb the tiny nerves (medial branches) that send pain signals from the facet joints. If the block is successful, you may be a candidate for radiofrequency ablation, a longer-lasting procedure. Explore this on our Medial Branch Blocks page.
Sacroiliac (SI) Joint Injections
The SI joints connect your spine to your pelvis. When inflamed, they can cause intense pain in the lower back, buttocks, or groin. An SI joint injection delivers an anesthetic and corticosteroid into the joint. If the anesthetic provides temporary relief, it confirms the diagnosis, which is considered the gold standard. The steroid then provides longer-lasting anti-inflammatory effects. Learn more about Sacroiliac Joint Injections.
Trigger Point Injections
Sometimes, back pain originates in the muscles. Chronically tight muscles can form painful knots called trigger points, causing localized or referred pain (myofascial pain). Trigger point injections deliver a local anesthetic, sometimes with a steroid, directly into the muscle knot. This helps the muscle relax, breaking the cycle of pain and spasm. For more details, visit our page on Trigger Point Injections.
Benefits, Risks, and What to Expect
Deciding on back pain injections is a significant step. We want you to be fully informed about the potential benefits, risks, and what the process involves.

Potential Benefits and Efficacy
The primary goal of back pain injections is to restore your quality of life. Key benefits include:
- Significant Pain Reduction: Many patients experience meaningful pain relief. For radicular pain from a herniated disc, up to 70% of patients report significant improvement.
- Improved Function and Mobility: With less pain, daily tasks like walking, bending, and sitting become manageable again.
- Avoiding Surgery: Injections can be a real alternative to more invasive procedures. For example, selective nerve root blocks may help up to 54% of patients avoid surgery.
- Window for Physical Therapy: By reducing pain, injections make it possible to engage in physical therapy, strengthen core muscles, and build long-term spinal support.
- Faster Return to Activities: All of this contributes to getting you back to work, hobbies, and family life sooner. Explore our comprehensive Chronic Back Pain Treatment options.
Risks and Potential Side Effects
While generally safe, back pain injections do have potential risks. We use fluoroscopic guidance and sterile techniques to minimize them. Common or possible side effects include:
- Temporary Pain Flare-Up: It’s normal to have increased soreness at the injection site for a day or two before the relief begins.
- Bleeding or Infection: Though uncommon, these are risks with any injection. We’ll provide instructions regarding blood thinners to reduce bleeding risk.
- Steroid-Related Effects: Corticosteroids can cause temporary facial flushing, insomnia, mood changes, or liftd blood sugar and blood pressure.
- Headache: A “spinal headache” can occur if the spinal sac is accidentally punctured, but it is treatable.
- Nerve Damage: This is rare, especially with X-ray guidance, but possible.
We limit the number of steroid injections to 2-3 per year for a specific area to avoid long-term risks like bone or muscle weakening. We will discuss all risks with you in detail before your procedure.
The Procedure and Recovery Process
Knowing what to expect can help ease any anxiety.
- Before the Procedure: We will give you specific instructions, which may include temporarily stopping blood thinners and fasting. You will need a driver if you receive sedation.
- During the Procedure: The process takes 15-30 minutes. You’ll lie on a table, and we’ll clean the area and numb your skin with a local anesthetic (this feels like a small pinch). Using X-ray guidance, we’ll place the needle precisely and inject the medication. You may feel pressure or a tingling sensation.
- After the Procedure: You’ll rest for 15-30 minutes before going home. We advise taking it easy for the rest of the day. The anesthetic provides some immediate relief, but the steroid typically takes 2-7 days to start working, with full effects around day 10. A temporary pain flare-up for 2-3 days is normal.
Relief can last from several weeks to several months or more, commonly three months or longer for lumbar epidurals. A follow-up appointment will be scheduled to assess your progress and plan the next steps, which usually involve physical therapy. Learn more about our approach to Pain Relief.
Making the Right Choice for Your Back Pain
Deciding if back pain injections are right for you is a process we take together. At California Pain Consultants, we start with conservative treatments and only recommend interventional options when necessary. The choice of injection depends on your specific diagnosis, overall health, and the true source of your pain. An accurate diagnosis is the critical first step. Learn more about our approach to Chronic Back Pain Treatment.
When Should You Consider an Injection?
Back pain injections are typically considered when simpler treatments have not provided enough relief. You may be a good candidate if:
- Your pain is chronic (lasting 12+ weeks) and significantly impacts your quality of life.
- Conservative care (medication, physical therapy, chiropractic care) has failed.
- A pain specialist has provided a specific diagnosis identifying the pain source.
- The pain prevents you from working, sleeping, or performing daily activities.
If this sounds familiar, injections could be an effective tool to break the pain cycle.
The Role of Physical Therapy with Back Pain Injections
Back pain injections work best when paired with physical therapy. The injection is not a standalone cure; it’s a tool to create an opportunity for healing. Severe pain creates a vicious cycle: you move less, muscles weaken, and stiffness increases. The injection breaks this cycle by reducing pain and inflammation, giving you a window to do the rehabilitative work that leads to lasting improvement.
Physical therapy helps you:
- Strengthen core muscles that support your spine.
- Improve flexibility to reduce stiffness and increase range of motion.
- Learn proper posture and body mechanics to protect your back.
This combination is key to maintaining long-term results and reducing the need for future injections. We view injections as a bridge to more effective rehabilitation. Learn more about our holistic approach to Back Pain Relief.
Latest Advancements in Back Pain Treatment
Pain management is constantly evolving. Beyond traditional steroid injections, we are exploring cutting-edge options in regenerative medicine and other minimally invasive techniques.
- Regenerative Medicine: Treatments like Platelet-Rich Plasma (PRP) and stem cell therapy use your body’s own healing mechanisms to repair damaged tissues. PRP uses concentrated platelets from your blood to stimulate repair, while stem cell therapy shows promise for regenerating damaged spinal discs.
- Minimally Invasive Techniques: Procedures like Basivertebral Nerve Ablation offer new ways to target chronic pain sources with incredible precision, providing relief without implants or altering spinal structure.
These advancements reflect our commitment to offering the most effective, evidence-based treatments available to our patients in San Diego, La Mesa, and Chula Vista.
Frequently Asked Questions about Injections for Back Pain
It’s natural to have questions when considering back pain injections. Here are answers to some of the most common concerns we hear from our patients.
How long does pain relief from a back injection last?
The duration of relief varies for each person and depends on the injection type and your specific condition. For epidural steroid injections, many patients experience relief for three months or more. Some find it lasts longer, while for others, it may be shorter. The goal is to provide a significant window of reduced pain that allows you to participate in physical therapy. This rehabilitation is what helps achieve longer-lasting results.
Are back injections painful?
Most patients report that the procedure is much less painful than they anticipated. We start by numbing the skin with a local anesthetic, which feels like a quick pinch or sting. After that, you’ll likely feel pressure rather than sharp pain during the injection itself. Our use of advanced X-ray guidance ensures precision, which also helps minimize discomfort. Communication is key, so please let us know if you feel any sharp pain during the procedure.
How many injections can I have per year?
For back pain injections containing corticosteroids, we are careful about frequency to avoid potential side effects. Typically, we limit injections to two to three per year for a specific area of the spine. This guideline helps minimize risks associated with long-term steroid use, such as the weakening of bones or tissues. Your doctor will create a treatment plan based on your response and overall health, using injections strategically as part of a comprehensive care plan for our patients in San Diego, La Mesa, and Chula Vista.
