Nerve Blocks & Diagnostic Injections
Best for patients who need targeted diagnosis, short-term relief, or a clearer answer about which nerve or joint is driving symptoms.
View pageRadiofrequency Ablation (RFA)
Radiofrequency ablation uses targeted heat to temporarily disrupt pain-transmitting nerves and is often considered after successful diagnostic blocks.
Overview
Targeted heat is used to temporarily disrupt pain-transmitting nerves, typically after diagnostic blocks have confirmed the source of pain.
When radiofrequency ablation is commonly used
Radiofrequency ablation is most appropriate when a diagnostic injection has already confirmed that a specific nerve is contributing to the patient's pain. It represents a logical next step in the treatment pathway - moving from a short-term diagnostic block toward a longer-lasting therapeutic result.
- Facet joint pain
- Chronic knee pain, including pain after knee replacement
- Chronic joint pain when other treatments have failed
- In selected situations, pulsed radiofrequency may be discussed when preserving nerve function is important
What to expect after the procedure
- Mild soreness, burning, or swelling
- A temporary increase in pain in some patients
- Pain relief may take up to 4 weeks
- Relief may last several months, depending on nerve regrowth
Radiofrequency ablation
Targeted heat can interrupt pain signals after diagnostic confirmation.
Aftercare and activity
- Apply ice packs for 10 to 15 minutes at a time
- Take acetaminophen (Tylenol) if needed
- Light activity the next day
- Gradual return to normal activity over 3 to 5 days
- Avoid strenuous activity for 1 week
Recovery timeline
Most patients can return to light activity the day after the procedure. Full benefit often builds over 2 to 4 weeks as nerve activity decreases. Strenuous exercise should be avoided for at least one week.
Risks and possible limitations
- Pain, bruising, or swelling
- Temporary numbness or weakness
- Infection or bleeding, which are uncommon
- Very rare nerve injury or allergic reaction
- Incomplete or temporary relief can still occur
Next Step
Discuss whether radiofrequency ablation is appropriate.
The clinic can review your symptoms, prior treatment, imaging, and whether this procedure fits into your care plan.
If you have a question after a recent procedure, call the clinic directly rather than waiting for an online response.
