Relieving Chronic Pain Through Targeted Heat Therapy
Living with chronic pain can significantly impact one’s quality of life. Fortunately, advances in medical technology have provided effective treatments to manage and alleviate persistent pain. One such treatment option is Radiofrequency Ablation (Hereafter referred to as ‘RFA’).
RFA utilises heat generated by radio waves to destroy targeted nerve tissue, preventing it from transmitting pain signals to the brain. This minimally invasive procedure has shown great promise in providing long-term pain relief for individuals suffering from various conditions, particularly those affecting the neck, lower back, and arthritic joints. In this article we will give an overview of all aspects involved with RFA and explain whether it could potentially be the right treatment for you.

Understanding Radiofrequency Ablation (RFA)
Radiofrequency ablation, also known as radiofrequency neurotomy, involves the use of radio waves to create a current that heats a small area of nerve tissue. By targeting specific nerves responsible for transmitting pain signals, RFA aims to reduce or eliminate pain, improve functionality, minimise reliance on pain medications, and potentially delay or avoid the need for surgery. This procedure has been successfully employed to manage chronic pain resulting from conditions such as arthritis of the spine, sacroiliac joint pain, neck and back pain, cancer pain, facial pain caused by trigeminal neuralgia, peripheral nerve pain, heart rhythm problems, and even tumours.
Identifying Candidates
Radiofrequency ablation is typically recommended for individuals who have experienced successful pain relief following a diagnostic nerve block injection. If other treatment options, such as pain medications and physical therapy, have failed to provide adequate relief, RFA may be considered. However, certain factors, such as pregnancy, active infections, and bleeding disorders, may exclude individuals from being eligible for this procedure. Consulting with a healthcare provider is crucial to determine if RFA is the right course of action.
The Procedure
During a radiofrequency ablation procedure, a specialised needle is precisely placed near the target nerve responsible for the pain. An electrode inserted into the needle delivers radio waves that generate heat, creating a lesion on the nerve. This lesion disrupts the transmission of pain signals, providing relief to the patient. It’s important to note that healthy surrounding nerves remain unaffected during the procedure, minimising the risk of complications.
Before the procedure, a thorough evaluation of the patient’s medical history and pain symptoms is conducted. Imaging tests, such as X-rays, may be ordered to assess the underlying cause and severity of the condition. A diagnostic block injection may be administered to confirm the source of the pain and assess the potential for pain relief with RFA. If the patient experiences a favorable response to the diagnostic block, the healthcare provider may proceed with recommending RFA as a suitable treatment option.
During the procedure, the patient lies on their stomach on a specialised X-ray table. Local anaesthesia is applied to numb the skin, ensuring minimal discomfort throughout the procedure. Using fluoroscopy, a real-time continuous X-ray, the healthcare provider guides a thin needle to the targeted nerve. To confirm the correct needle placement, a microelectrode is inserted through the needle, and the patient is asked to provide feedback regarding any tingling sensation or discomfort. Once the target location is confirmed, a local anaesthetic is injected to numb the area, followed by the delivery of radiofrequency current through the needle to generate heat and create the lesion on the nerve. The procedure can treat multiple nerves if necessary, and the duration typically ranges from 15 minutes to two hours, depending on the location and complexity of the treatment.
Recovery and Outlook
After the radiofrequency ablation procedure, patients can return home shortly thereafter, but they must have someone drive them. Resting is recommended initially, and strenuous activities should be avoided for the first 24 hours. Over the following days, mild soreness, pain, or muscle spasms at the treatment site may be experienced. Pain medication prescribed by the healthcare provider can help manage discomfort during the recovery period. Applying ice packs intermittently for 20 minutes at a time can also help alleviate pain and reduce swelling.
Patients may be recommended to undergo physical therapy to regain strength and flexibility. A follow-up appointment will be scheduled to monitor the progress and address any concerns or questions that may arise.
Risks and Benefits
Radiofrequency ablation offers several advantages for pain management. Patients often experience significant pain relief, thereby reducing their reliance on pain medications. Since RFA is a minimally invasive procedure, it does not involve surgery, resulting in minimal recovery time and allowing patients to return to their regular activities within a day or two. The procedure also carries a low risk of complications, such as infection or bleeding, although there is a slight chance of temporary nerve damage or increased pain in some cases.
Effectiveness for Pain Management
The efficacy of radiofrequency ablation varies from person to person and depends on the specific cause, location, and severity of the pain. While most individuals experience some level of pain relief following RFA, the duration of relief can range from six months to several years. Nerves treated with RFA may regenerate over time, typically between six and 12 months after the procedure. In such cases, the procedure can be repeated if necessary.
Knowing When to Seek Medical Attention
After the RFA procedure, patients should be aware of certain signs that warrant contacting their healthcare provider. Severe pain, redness, or swelling at the needle insertion site, as well as increased weakness or numbness in an arm or leg, should be promptly reported.
In Summary
Radiofrequency ablation has emerged as a valuable option for individuals suffering from chronic pain. By precisely targeting and disrupting the transmission of pain signals, RFA offers long-term relief and improved functionality, reducing the need for pain medications and potentially avoiding surgery. As with any medical procedure, consultation with a healthcare provider is essential to determine if radiofrequency ablation is the right course of treatment for each individual case. With its minimal invasiveness and potential for significant pain reduction, RFA holds promise as a valuable tool in pain management and improving the quality of life for those with chronic pain conditions.
