The most important clinical decision with Radiofrequency Ablation Foot isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.
What Is Radiofrequency Ablation for the Foot?

Radiofrequency ablation (RFA) is a minimally invasive procedure that uses heat energy generated by high-frequency electrical current to disrupt nerve function. In the foot, it’s most commonly used to treat chronic pain from interdigital neuromas (Morton’s neuroma), heel nerve entrapments (inferior calcaneal nerve, medial calcaneal nerve), small fiber neuropathy, and post-surgical nerve pain.
Under ultrasound or fluoroscopic guidance, a specialized needle is placed adjacent to the target nerve. The needle tip generates precisely controlled heat (80–90°C) that coagulates the nerve protein, disrupting pain signal transmission. The procedure is performed under local anesthesia in an outpatient setting and takes approximately 20–45 minutes per area.
RFA for foot pain has gained significant clinical adoption over the past decade as an alternative to surgical neurectomy. Unlike surgery, RFA is reversible in the sense that nerves can partially regenerate — though the goal is typically 12–24 months of pain relief during which conservative treatments can take effect.
Conditions Treated with RFA in the Foot
Morton’s neuroma — One of the most successful RFA applications in the foot. For neuromas that haven’t responded to steroid injections (usually 2–3 injections), RFA can provide 1–2 years of pain relief without the complications of surgical neurectomy (permanent numbness, stump neuroma formation). Success rates of 60–80% are reported in published case series.
Plantar fasciitis / heel pain — Cryoablation and RFA of the inferior calcaneal nerve branches are used for refractory plantar fasciitis. The medial calcaneal nerve carries the pain signal from the heel — disrupting it reduces the pain cycle while underlying structural healing continues.
Tarsal tunnel syndrome — When nerve decompression surgery is not desired or appropriate, RFA of specific tibial nerve branches in the tarsal tunnel can reduce burning, tingling, and numbness symptoms.
Post-surgical nerve pain — Stump neuromas and scar-entrapped nerves after bunion, hammer toe, or ankle surgery can be treated with targeted RFA under ultrasound guidance, avoiding the need for revision surgery.
What to Expect from an RFA Procedure
RFA is an outpatient procedure performed under local anesthesia. You’ll feel the numbing injection (similar to a dental block) and may feel pressure during needle placement, but the actual ablation is painless. The procedure takes 20–45 minutes, and you can typically drive yourself home afterward.
Post-procedure, expect 3–7 days of soreness at the treatment site — this is normal inflammation from the ablation process. Some patients experience temporary increased nerve sensitivity (dysesthesias) during the first 2 weeks as the nerve responds to treatment. Full effect is typically assessed at 6–8 weeks post-procedure.
RFA is not a permanent cure. As nerves regenerate, pain may return — usually in 12–24 months. However, many patients require only one or two treatments and find that the pain-free interval allows their underlying condition to heal. For neuromas, RFA can be repeated, and patients who prefer it over surgery often do 1–2 treatments every 1–2 years.
Dr. Tom's Product Recommendations
Doctor Hoy’s Natural Pain Relief Gel
⭐ Highly Rated
Post-procedure topical pain management without NSAIDs. Safe to use after RFA without interfering with the tissue response.
Dr. Tom says: “I recommend Doctor Hoy’s for managing post-RFA soreness. It’s effective for localized nerve and soft tissue discomfort.”
Post-procedure soreness, chronic nerve pain management between treatments
Open needle site — wait 24–48 hours post-procedure before applying

CURREX RunPro Insoles
⭐ Highly Rated
Biomechanical insoles to reduce ongoing nerve compression at the ball of the foot during RFA recovery. Metatarsal pad placement offloads the neuroma zone.
Dr. Tom says: “Reducing mechanical neuroma compression post-RFA extends the duration of pain relief. CURREX with proper metatarsal positioning is my top choice.”

Dr. Tom Biernacki’s Recommendation
RFA is a powerful tool for patients with Morton’s neuroma who want to avoid surgery. I’ve seen excellent results in appropriately selected patients — particularly those with confirmed neuroma on MRI or ultrasound who’ve had 2–3 cortisone injections without lasting relief. If you’re in that category, RFA is worth a consultation.

Frequently Asked Questions
How long does radiofrequency ablation last for foot pain?
Typically 12–24 months. As the nerve regenerates, pain may return. The procedure can be repeated.
Is radiofrequency ablation painful?
The local anesthetic injection causes brief stinging. The ablation itself is painless. Post-procedure soreness lasts 3–7 days.
Is RFA covered by insurance for foot pain?
Coverage varies. Morton’s neuroma and tarsal tunnel syndrome RFA have the best insurance coverage. Check with your insurer and podiatrist.
