If you’ve been living with chronic pain and still don’t have clear answers, you’re not alone. Many patients come to us after trying physical therapy or other treatments without lasting relief. That’s where interventional pain management and our interventional pain management services can make a real difference, not just by easing symptoms, but by helping identify the exact source of your pain.
At Goodman Campbell, nerve blocks are part of a precise, evidence-based diagnostic process. Our aim is to uncover the root cause of your pain, not merely mask it.
What Is a Diagnostic Nerve Block and How Is It Different From a Treatment?
A diagnostic nerve block is a targeted nerve block injection used as a diagnostic tool. Instead of simply providing pain relief, it serves as a diagnostic tool that helps your care team determine which nerve, joint, or spinal structure may be causing your symptoms.
In many cases, a spine surgeon may recommend a diagnostic nerve block when imaging studies and physical examination findings do not tell the full story. The information gained from the injection can help confirm whether a specific area is responsible for your pain and may play an important role in treatment planning, including determining whether surgery is likely to address your symptoms.
Using imaging guidance, an interventional pain management physician places a small amount of local anesthetic at a precise injection site, near a specific nerve or affected nerve. If your pain improves, it tells us that the nerve is likely responsible for sending those pain signals.
What Is the Difference Between a Diagnostic and a Therapeutic Nerve Block?
A therapeutic nerve block is designed to provide longer-lasting pain relief and help reduce inflammation.
A diagnostic nerve block, on the other hand, is about clarity. It helps answer questions such as:
- Which pain patterns are tied to which nerves?
- What is the underlying cause of your ongoing pain?
- Which particular nerve is responsible for sending those pain signals?
- Would treating a specific area be likely to improve your pain?
Often, both approaches work together as part of a larger treatment plan.
How Does a Nerve Block Help Find the Source of Your Pain?
Pain doesn’t always originate where you feel it. For example, nerve pain in the hip may actually stem from the spinal column. By temporarily interrupting pain messages along a particular nerve, we can see how your body responds. If your symptoms improve, we’ve likely identified the exact source.
This is especially helpful in chronic back pain diagnosis, where multiple structures, such as discs, joints, or peripheral nerves, may be involved.
What Do the Results Mean if the Nerve Block Does or Doesn’t Work?
Your nerve block results guide the next steps:
- If you experience pain relief, we’ve identified the source and can focus treatment there.
- If you don’t experience pain relief, that nerve likely isn’t the cause, and we continue investigating.
Either way, the information moves your care forward.
What Types of Nerve Blocks Are Used to Diagnose Spine and Nerve Pain?
There are several types of nerve blocks we use in interventional spine care, including:
- Selective nerve root block for pinpointing irritated spinal nerves
- Medial branch block for facet joint-related pain
- Blocks around the sacroiliac joints
Each is chosen based on your symptoms and suspected pain conditions.
What Happens After a Diagnostic Nerve Block?
These procedures are performed on an outpatient basis, so you can go home the same day. We’ll ask you to track your symptoms closely. Specifically, we want to understand how much relief you feel, how long it lasts, and how it affects your daily activities. This feedback is critical in shaping your treatment options.
This information is an important part of the diagnostic process. Your response to the injection helps confirm whether a specific nerve, joint, or other spinal structure is responsible for your pain and helps guide the most appropriate treatment plan.
In some cases, we may recommend additional nerve blocks to confirm findings or further refine your spine pain diagnosis.
Can a Nerve Block Lead to Surgery?
Yes. In some cases, diagnostic nerve blocks are used to help determine whether surgery is likely to address the source of a patient’s symptoms.
If a nerve block provides significant relief, it can help confirm that a specific nerve root, joint, or spinal structure is the pain generator. This information gives your care team greater confidence in recommending the most appropriate treatment, whether that involves continued conservative care, interventional pain management, or surgery.
