Nerve Block
UNDERSTANDING THE SCIENCE
What is a nerve block?
TREATMENT TYPES
Types of Nerve Blocks
Medial Branch Blocks
- Target the medial branch nerves that supply the facet joints of the spine.
- Used to diagnose and treat facet joint arthritis in the cervical, thoracic, or lumbar spine.
- Often performed prior to radiofrequency ablation (RFA) to confirm the correct nerves are causing pain.
Epidural Steroid Injections (ESI)
- Deliver steroids and anesthetic into the epidural space around the spinal cord.
- Commonly used for lumbar, cervical, or thoracic radicular pain caused by herniated discs, spinal stenosis, or nerve root irritation.
- Reduces inflammation and provides pain relief that enables patients to participate in rehabilitation with our in-house physical therapists.
Stellate Ganglion Block
- Targets the stellate ganglion, a collection of nerves in the neck.
- Often used for complex regional pain syndrome (CRPS), vascular pain, or certain chronic head and neck pain.
- Helps with sympathetic nerve-mediated pain, such as cold hands or Raynaud’s phenomenon.
Peripheral Nerve Blocks
- Target specific nerves outside the spine, such as the femoral, sciatic, or brachial plexus nerves.
- Commonly used for post-surgical pain, localized chronic pain, or joint pain.
- Provides both diagnostic insight and therapeutic relief, and integrates seamlessly with in-office therapies to improve recovery.
Sacroiliac (SI) Joint Blocks
- Target nerves supplying the sacroiliac joint in the lower back and pelvis.
- Used to diagnose or treat SI joint dysfunction, which can cause chronic low back or buttock pain.
- Often combined with physical therapy and adjunctive modalities at Compass to maximize long-term outcomes.

How Nerve Blocks Work
Nerve blocks work by interrupting the transmission of pain signals from the affected nerve to the brain. The medication used typically includes:
- Local anesthetic: Temporarily numbs the nerve for immediate relief.
- Corticosteroid: Reduces inflammation, which can provide longer-lasting relief.
- Other agents: Such as saline or neurolytic agents in specialized cases.


- The patient is positioned comfortably in our state-of-the-art procedural suite.
- The target nerve or region is identified using fluoroscopy or ultrasound guidance for precise needle placement.
- Medication is injected around the target nerve(s).
- Patients may experience immediate numbing, followed by gradual reduction in inflammation over several days.
- Our care team coordinates directly with your in-house physical therapist to ensure post-procedure rehabilitation is optimized.
Some patients may also receive red-light therapy or PEMF sessions after their procedure to enhance tissue healing, reduce inflammation, and improve overall results.
IDEAL CANDIDATES
Who Is a Good Candidate?
Nerve blocks may be recommended for patients who:
- Have chronic pain that has not responded to medications, physical therapy, or lifestyle changes.
- Need diagnostic information to pinpoint the source of pain.
- Are seeking to reduce inflammation or nerve irritation in a specific area.
- Want to avoid or delay surgery while improving function and quality of life.
Not recommended if:
- You have an active infection near the injection site.
- You have uncontrolled bleeding disorders.
- You cannot safely remain still during the procedure.
At Compass Pain and Wellness, every patient undergoes a comprehensive evaluation, and your treatment plan is fully integrated with our in-house therapy and rehabilitation team for the best possible outcomes.

THE PROCESS
What to Expect on Procedure Day
Preparation:
- Review of medical history and imaging studies.
- Explanation of the specific nerve block and expected outcomes.
During the Procedure:
- Skin is cleaned and numbed.
- Imaging guidance ensures precise needle placement.
- Medication is injected around the target nerve(s).
After the Procedure:
- Patients are monitored briefly, then typically go home the same day.
- Mild soreness or bruising at the injection site is normal.
- Temporary numbness or tingling is expected.
- You physician will coordinate with your in-house physical therapist, and adjunctive therapies like PEMF or red-light therapy may be scheduled to maximize recovery.
-
Most patients can resume light activities immediately, but avoid strenuous activity for 24–48 hours.
-
Pain relief may be immediate (from anesthetic) or develop over several days (from steroid effect).
-
Some patients require multiple injections spaced over weeks to achieve optimal results.
-
Nerve blocks at Compass are always integrated into a personalized rehabilitation plan, including therapy, lifestyle counseling, and adjunctive therapies to improve long-term outcomes.

While nerve blocks are generally safe, potential complications include:
-
Infection at the injection site
-
Bleeding or bruising
-
Temporary nerve irritation
-
Allergic reaction to medication
-
Rare complications depending on the block location and underlying health
All procedures at Compass Pain and Wellness are performed with strict safety protocols and our multidisciplinary team ensures close follow-up for optimal outcomes.

-
Many patients experience significant pain relief, improved mobility, and the ability to participate in rehabilitation.
-
Diagnostic nerve blocks provide critical information to guide future treatments, such as RFA or spinal cord stimulation.
-
Results vary depending on the type of block, location, and underlying condition.
-
With Compass’ coordinated care model, patients often experience enhanced recovery, faster functional improvement, and a better overall experience than traditional settings.
