Radiofrequency ablation (RFA) is a minimally invasive procedure used to treat chronic pain, certain cancers, and irregular heart rhythms (arrhythmias). While it’s widely regarded as safe and effective, it’s important to understand the potential side effects before undergoing the procedure.
In this blog post, we’ll delve into everything you need to know about radiofrequency ablation side effects, their causes, and how to manage them.
Key Takeaway:
- Radiofrequency ablation (RFA) is a minimally invasive procedure used to treat chronic pain, arrhythmias, and tumors.
- Common side effects include mild pain, swelling, bruising, and temporary nerve irritation.
- Rare complications may include infections, nerve damage, or organ injury (in tumor ablation).
- Most side effects are mild and resolve within a few days to weeks.
- Consult your doctor immediately if you experience severe pain, signs of infection, or unusual symptoms.
- Following pre- and post-procedure care instructions can minimize risks and aid recovery.

What is Radiofrequency Ablation
Radiofrequency ablation involves using heat generated by radio waves to destroy targeted nerve tissues or abnormal cells. It’s commonly used for:
- Chronic Pain: Especially in the neck, back, and joints.
- Cardiac Issues: Such as arrhythmias like atrial fibrillation.
- Cancer Treatment: For tumors in the liver, kidney, or lungs.
The procedure is generally safe, but like any medical intervention, it comes with potential risks and side effects.

Common Side Effects of Radiofrequency Ablation
While side effects are uncommon and usually mild, some patients may experience the following:
1. Pain or Discomfort
- Cause: The procedure involves heating tissues, which can lead to localized irritation.
- Symptoms: Soreness or tenderness at the treatment site.
- Management: Over-the-counter pain medications like ibuprofen or acetaminophen can help. Pain usually subsides within a few days.

2. Swelling and Bruising
- Cause: The insertion of needles or catheters into the skin can cause minor tissue trauma.
- Symptoms: Visible swelling or bruising around the treated area.
- Management: Applying an ice pack for 15–20 minutes every few hours can reduce swelling.
- Learn more here
3. Nerve Damage
- Cause: The heat from the procedure may inadvertently affect nearby healthy nerves.
- Symptoms: Numbness, tingling, or weakness in the affected area.
- Management: In most cases, nerve damage is temporary, but physical therapy may be recommended for prolonged symptoms.

4. Burns or Skin Sensations
- Cause: Heat from the radiofrequency waves may affect the skin near the insertion site.
- Symptoms: Mild burns, tingling, or a warm sensation.
- Management: Topical creams and keeping the area clean can aid healing.
- Learn more here
5. Infection
- Cause: Bacteria entering the site of needle insertion.
- Symptoms: Redness, swelling, fever, or pus around the treated area.
- Management: Antibiotics are usually prescribed for infections. Severe cases may require medical attention.

6. Bleeding
- Cause: Blood vessel injury during needle or catheter insertion.
- Symptoms: Unusual or prolonged bleeding at the site.
- Management: Apply firm pressure to the site and consult your doctor if it doesn’t stop.

Rare but Serious Side Effects
Although rare, radiofrequency ablation may lead to more serious complications (you can find more information here.). These include:
1. Neuroma Formation
- Cause: Overgrowth of nerve tissue due to incomplete ablation.
- Symptoms: Severe or chronic pain.
- Management: Follow-up treatments or medication may be necessary.
2. Allergic Reactions
- Cause: Reaction to anesthesia, contrast dye, or materials used in the procedure.
- Symptoms: Rash, itching, or difficulty breathing.
- Management: Immediate medical attention is required for severe reactions.
3. Organ Damage (For Tumor Ablation)
- Cause: Heat unintentionally affecting nearby organs.
- Symptoms: Vary depending on the affected organ.
- Management: Prompt medical evaluation and treatment.
4. Arrhythmias
- Cause: RFA for cardiac issues may sometimes trigger abnormal heart rhythms.
- Symptoms: Palpitations, dizziness, or chest pain.
- Management: Your cardiologist may recommend medication or additional procedures.
How to Minimize Side Effects of Radiofrequency Ablation
- Choose an Experienced Specialist: An experienced doctor minimizes the risk of complications.
- Follow Pre-Procedure Instructions: Avoid eating, drinking, or taking certain medications as instructed.
- Post-Procedure Care: Keep the treated area clean and avoid strenuous activities.
When to Contact a Doctor
While most side effects are mild, seek immediate medical attention if you experience:
- Persistent or worsening pain.
- Fever or signs of infection.
- Severe numbness, weakness, or difficulty moving.
- Unusual heart symptoms like chest pain or shortness of breath.
Neuritis After Radiofrequency Ablation Treatment
- Neuritis, or nerve inflammation, can occur if nearby nerves are irritated during the procedure.
- Symptoms include sharp, burning pain or heightened sensitivity.
- Management: Anti-inflammatory medications and physical therapy can help relieve symptoms.
Radiofrequency Ablation Cost
- The cost varies by region, procedure type, and insurance coverage.
- In the U.S., the average cost ranges from $2,000 to $7,000 per session.
- Insurance often covers RFA if it’s medically necessary and approved by a doctor.
Worse Pain After Radiofrequency Ablation
- Temporary pain flare-ups are common due to nerve irritation or tissue healing.
- Severe or prolonged pain may indicate complications like neuritis or improper nerve targeting.
- Contact your doctor if the pain doesn’t subside after a few weeks.
Radiofrequency Ablation Uses
- Chronic Pain: Treats pain in the neck, back, and joints (e.g., facet joint pain).
- Cardiac Issues: Treats arrhythmias like atrial fibrillation.
- Cancer Treatment: Destroys tumors in the liver, kidneys, or lungs.
- Cosmetic Treatments: Used for skin tightening and wrinkle reduction.
Massage After Radiofrequency Ablation
- Avoid massage on the treated area for at least 1–2 weeks to prevent irritation.
- Gentle massages on surrounding muscles may help with soreness or tension.
- Always consult your doctor before resuming massage therapy.
Leg Numbness After Radiofrequency Ablation
- Numbness may occur if the ablation affects nearby sensory nerves.
- It is usually temporary and resolves in a few weeks.
- Persistent numbness should be evaluated by your doctor.
How to Sleep After Radiofrequency Ablation
- Sleep in a position that minimizes pressure on the treated area.
- Use supportive pillows to stay comfortable, especially for neck or back treatments.
- Avoid strenuous movements before bedtime to reduce discomfort.
How Long Does It Take for Nerves to Die After Radiofrequency Ablation?
- Nerve destruction begins immediately during the procedure.
- Full effects are usually noticeable within 7 to 10 days.
- Pain relief can last 6 months to 2 years, depending on nerve regrowth.
Exercise After Radiofrequency Ablation: What You Need to Know
- Avoid strenuous exercise for at least 48–72 hours after the procedure.
- Light activities like walking can be resumed earlier if approved by your doctor.
- Gradually reintroduce more intense workouts over 2–4 weeks, depending on your recovery.

Frequently Asked Questions
1. How long do side effects of radiofrequency ablation last?
Most side effects, such as soreness or swelling, resolve within a few days to weeks. Severe complications are rare and may require longer recovery.
2. Is radiofrequency ablation painful?
The procedure itself is performed under local anesthesia or sedation, so pain is minimal. Post-procedure soreness is common but manageable.
3. Can radiofrequency ablation cause permanent nerve damage?
Permanent nerve damage is extremely rare. Temporary numbness or tingling is more common and usually resolves on its own.
