A Radiofrequency Ablation (RFA) uses gentle heat to interrupt nerve signals or destroy abnormal tissue. It is a direct, image-guided way to manage chronic pain or treat specific tumors without major surgery.
Common Indications for RFA
Your doctor may recommend RFA to:
- Manage chronic neck or lower back pain caused by arthritis in the spine.
- Treat pain coming from the sacroiliac (SI) joint.
- Destroy small tumors in the liver, kidney, lung, or bone.
What exactly does RFA do?
An electrical current passes through a special needle, heating the tip. If treating pain, this heat burns the tiny nerve carrying the pain signal, stopping it from reaching your brain. If treating a tumor, the heat completely destroys the abnormal cells.
What happens during the procedure?
You will lie down near a CT scanner or an ultrasound machine. After receiving a local anesthetic and some relaxing IV medicine, the doctor uses the live images to guide a thin needle directly to the nerve or tumor. Once the needle is perfectly positioned, the tip is heated to create the targeted burn.
Will it be painful?
The numbing medicine prevents sharp pain during the procedure, but you may feel a warm, tight, or tingling sensation when the heat is applied. Afterward, it is very common to feel like you have a "sunburn" under your skin or experience some muscle soreness that can last for a week or two. This is a normal part of the healing process.
Conclusion
RFA is an excellent option for patients seeking pain relief or tumor treatment with a brief recovery period. While full pain relief may take a few weeks to set in, the procedure allows most people to return to their normal lives the very next day.
