How Long Does it Take for Nerves to Die After RFA?

Radiofrequency ablation (RFA) has become a go-to treatment option for alleviating chronic nerve pain. This minimally invasive procedure uses controlled heat to disrupt problematic nerve signals. But how long does it actually take for the nerves to die and pain relief to kick in after having radiofrequency ablation? Let’s find out.

Expected Timeline for Pain Relief

In most cases, patients report a gradual decrease in pain over the first 1-2 weeks following the procedure. Maximum pain relief is generally achieved within 2-3 weeks after radiofrequency ablation.

However, the precise timeline can vary from patient to patient depending on factors like:

  • Location of the nerves being treated
  • Type of nerves being targeted
  • Individual’s overall health and healing capacity
  • Provider’s technique and precision

During the first few weeks, it’s common to experience some tenderness, swelling, bruising or numbness around the ablation site as the nerves heal.

Signs the Nerves Are Dying

Several signs indicate that the radiofrequency ablation successfully damaged the target nerves:

  • Gradual decrease in pain levels
  • Numbness in the regions where pain signals originate
  • Loss of sensation in the treated area
  • Weakness or clumsiness as nerve function diminishes

These effects may start small but become more pronounced over the 2-3 weeks following the procedure as the nerves fully die off.

How the Body Responds?

The body responds to the induced nerve damage in a few key ways:

  • The damaged nerves can no longer effectively transmit pain signals to the brain. This reduces the perception of pain.
  • There may be some inflammation, swelling, and bruising around the ablation site as the body begins healing. This typically resolves within a few weeks.
  • Numbness, tingling, or weakness can occur as nerve function is disrupted.
  • Nearby nerves may sprout new connections over time to compensate for the loss of the ablated nerves.

Risks and Side Effects

While considered minimally invasive, radiofrequency ablation still carries some risks and potential side effects including:

  • Infection at the needle insertion sites
  • Accidental damage to blood vessels or non-target nerves
  • Increased pain or numbness if nerves are improperly targeted
  • Bleeding and bruising at the ablation site

However, when performed by an experienced doctor, the risk of complications is very low. Most patients recover quickly with minimal side effects.

YOUR ROADMAP TO AVOID THYROID SURGERY

Recovering from RFA

The recovery process after radiofrequency ablation is relatively quick. Most people can go back home on the same day as the procedure. Soreness and tenderness may persist for 1-2 days but can be managed with over-the-counter pain medication.

Patients are usually able to resume their normal daily activities within 24 hours after the ablation. Strenuous exercise and exertion should be avoided for at least a week post-procedure.

It’s crucial to follow all post-procedure care instructions from your doctor to help minimize risks and support proper healing.

How Long Does Pain Relief Last?

Most patients achieve significant pain relief for 6 to 12 months or longer following radiofrequency ablation. However, because the nerves are not completely destroyed, there is potential for the pain signals to eventually regenerate over time.

If pain returns, the radiofrequency ablation can be repeated to deliver longer-lasting relief. Some people undergo regular ablation procedures every 8-12 months to keep nerve pain under control.

Who May Not Be a Candidate for RFA?

Radiofrequency ablation works best for certain chronic nerve pain conditions. However, it may not be advisable or effective for certain patients including:

  • Those with an active infection
  • People with bleeding disorders
  • Anyone allergic to local anesthetics used in the procedure
  • Areas where nerves run close to major blood vessels
  • Patients who are pregnant

Always consult your doctor to determine if you are a good candidate for radiofrequency ablation based on your specific condition and health profile.

The Bottom Line

Radiofrequency ablation offers a minimally invasive option for long-term relief from chronic nerve pain. Within 2-3 weeks, most patients experience maximal pain relief as the damaged nerves are no longer able to effectively transmit pain signals.

Relief can last 6 months or longer in many cases. While not always permanent, radiofrequency ablation is an effective way to “turn off” problematic pain signals and improve quality of life. Talk to your doctor to learn more about the benefits and risks of this procedure.
