What Is Pain Injection Therapy — and Could It Work for You?
Pain injection therapy is a minimally invasive treatment that delivers medication directly to the source of pain — reducing inflammation, blocking pain signals, or promoting healing without surgery.
Here’s a quick overview of what you need to know:
- What it is: Targeted injections of medication (steroids, anesthetics, or biologics) into painful joints, nerves, or soft tissue
- What it treats: Back pain, arthritis, sciatica, tendinitis, chronic migraines, and more
- How it works: Medication is delivered precisely to the pain source, often guided by imaging like fluoroscopy or ultrasound
- Who it’s for: People whose pain hasn’t responded to rest, oral medications, or physical therapy
- Key benefit: Longer-lasting relief than oral medications — often weeks to months — with fewer systemic side effects
Living with chronic pain is exhausting. It limits what you can do, affects your mood, and makes even simple daily tasks feel like a battle. If you’ve tried medications, rest, and physical therapy without real relief, you’re not alone — and you’re not out of options.
Pain injection therapy sits in a powerful middle ground: more targeted than a pill, far less drastic than surgery. It can calm an inflamed joint, quiet an irritated nerve, or give you just enough relief to finally get moving again. For many patients, that window of relief is exactly what they need to start rebuilding their strength and quality of life.
I’m Dr. Zach Cohen, double board-certified in Anesthesiology and Chronic Pain, and pain injection therapy is at the core of my clinical practice — from epidural steroid injections and nerve blocks to regenerative treatments like PRP. I’ll walk you through everything you need to know to make a confident, informed decision about your care.

The Science Behind Pain Injection Therapy
At its core, pain injection therapy is about precision. When you take an oral medication, it has to travel through your entire digestive system and bloodstream before a small fraction reaches the area that actually hurts. By contrast, an injection places the “fire extinguisher” directly on the “fire.”
The primary mechanism involves delivering potent anti-inflammatory agents or numbing medications to specific anatomical structures. This is often referred to as a Therapeutic Injections for Pain Management approach. By reducing localized swelling and chemical irritation around nerves, we can effectively “reset” the pain threshold.
Our primary goals for this therapy include:
- Diagnostic Accuracy: Confirming the exact structure causing your pain.
- Inflammation Reduction: Cooling down “hot” joints or nerves.
- Interrupting Pain Signals: Blocking the electrical messages sent to the brain.
- Restoring Function: Providing a window of relief so you can participate in physical therapy.
Common Applications of Pain Injection Therapy
We see a wide variety of conditions in our San Diego and La Mesa clinics that respond beautifully to these treatments. Whether it is wear-and-tear from age or an acute sports injury, injections offer a non-surgical path forward.
Research shows that nearly 80 percent of spine patients are able to recover with nonsurgical treatment. Common conditions treated include:
- Arthritis: Reducing friction and inflammation in the knee, hip, or shoulder.
- Sciatica: Calming the nerve roots in the lower back that cause radiating leg pain.
- Tendinitis: Treating “tennis elbow” or Achilles issues that haven’t healed with rest.
- Herniated Discs: Delivering Epidural injections for back pain to reduce the chemical irritation caused by disc material touching a nerve.
- Chronic Migraines: Using specialized blocks to quiet overactive pain pathways.
Preparing for Your Pain Injection Therapy
Preparation is key to a safe and smooth experience. During your initial pre-procedural evaluation, we will review your full medical history and current medications.
One of the most important steps is discussing blood thinners. We may ask you to stop certain anticoagulants a few days prior to minimize the risk of bleeding. We also adhere to strict Notice of Privacy Practices to ensure your health data is protected.
On the day of your procedure:
- Clothing: Wear loose, comfortable clothing. We may provide a gown depending on the injection site.
- Fasting: Some procedures involving sedation may require you to avoid food or drink for a few hours.
- Transportation: For many spinal or sedated procedures, you must arrange for a ride home, as you cannot drive for 24 hours.
Targeted Relief: Exploring the Most Common Injection Types
Not all “shots” are the same. Your treatment is tailored to the specific tissue that is causing the trouble. For instance, myofascial pain and trigger points occur in about 85% of people at some point in their life. For these patients, a simple Trigger Point Injections can release a muscle knot that has been causing referred pain for months.
Other common types include:
- Cortisone Shots: The “gold standard” for quick inflammation relief in joints like the shoulder or knee.
- Facet Joint Blocks: Targeting the tiny joints that connect your vertebrae. We often say these act like “WD40 on a rusty door hinge.”
- Sacroiliac (SI) Joint Injections: Treating the area where your spine meets your pelvis.
- Radiofrequency Ablation (RFA): A more advanced step where we use heat to “turn off” a nerve’s ability to send pain signals. More than 70% of patients treated with RFA experience significant relief that can last up to two years.
Epidural Steroid Injections (ESI)
If you struggle with spinal stenosis or radiculopathy (pinched nerves), an ESI might be the right choice. We deliver a mixture of an anesthetic for immediate relief and a corticosteroid for long-term anti-inflammatory action into the epidural space.
This space surrounds your spinal cord and the nerves that branch out from it. By bathing these nerves in medication, we can reduce the swelling that causes “shooting” pains. For those looking for deeper reading on managing these conditions, resources like A Book: Mayo Clinic Guide to Arthritis offer excellent insights into how inflammation affects our mobility.
Botox and Specialized Blocks
Beyond traditional steroids, we utilize chemodenervation and specialized nerve blocks for complex cases. BOTOX® Injections are FDA-approved for chronic migraines, working to prevent pain before it even starts by blocking neurotransmitters.
We also perform:
- Occipital Nerve Blocks: For headaches that start at the base of the skull.
- Stellate Ganglion Blocks: Used for complex regional pain syndrome (CRPS) or certain types of nerve-related facial pain.
- Sympathetic Blockade: To help differentiate between somatic and sympathetic pain sources.
Safety and Precision: The Role of Imaging Guidance
In the past, many injections were done “blind” based on anatomical landmarks. Today, we prioritize safety and accuracy by using real-time imaging.
Fluoroscopy (a type of live X-ray) and ultrasound guidance allow us to see the needle move through the tissue in real-time. This ensures the medication is placed exactly where it needs to be, avoiding blood vessels and unintended nerves.
| Feature | Guided Injection (Fluoroscopy/Ultrasound) | Unguided (Blind) Injection |
|---|---|---|
| Accuracy | Extremely High (>95%) | Variable (60-80%) |
| Safety | High (Vessel avoidance) | Moderate |
| Medication Volume | Targeted (Less needed) | Higher (To ensure coverage) |
| Diagnostic Value | Definitive | Limited |
We take radiation safety seriously. A typical skin entrance dose rate from fluoroscopy is about 30 mGy/min, and we use the lowest possible settings to achieve a clear image. Additionally, 90% of adverse effects from radiocontrast media occur within 15 minutes of exposure, so we monitor you closely in our clinic following the procedure.
Beyond Steroids: Regenerative Medicine and Orthobiologics
While steroids are excellent for reducing inflammation, they don’t necessarily “fix” damaged tissue. This is where orthobiologics or regenerative injection therapy comes in.
These treatments use your body’s own cells to jumpstart the healing process. Common options include:
- Platelet-Rich Plasma (PRP): We take a small sample of your blood, concentrate the platelets (which are full of growth factors), and inject them into a damaged tendon or joint.
- Stem Cell Therapy: Utilizing concentrated cells from your own tissue to promote repair in arthritic joints.
Unlike steroids, which can sometimes weaken tendons if overused, regenerative medicine aims for long-term tissue repair. While these are often not covered by insurance, many patients find them to be a worthwhile investment in their long-term health.

Frequently Asked Questions About Pain Injections
How long does the pain relief typically last?
This varies by the type of injection. A local anesthetic may only last a few hours, but it serves as a “test” to see if we’ve hit the right spot. Corticosteroids typically take 2-7 days to “kick in” and can provide relief for several months. Advanced procedures like Radiofrequency Ablation can last one to two years.
Are these procedures covered by insurance?
Most traditional injections, such as epidural steroid injections and facet blocks, are covered by Medicare, Tricare, and most commercial insurance plans. Regenerative treatments like PRP are typically “self-pay.” Our staff in San Diego and Chula Vista will verify your benefits before your appointment.
What are the most common side effects?
The most common issue is a “steroid flare,” where the injection site feels more painful for 24-48 hours. This occurs in about 10% of patients. Other side effects include temporary numbness (from the local anesthetic), minor bruising, or a temporary rise in blood sugar for diabetic patients.
