Radiofrequency for Chronic Pain: A Modern, Safe and Effective Solution
Do you suffer from chronic pain in your back, neck, knees or other joints? If medications no longer work as well as they used to, or if you are looking for a non-surgical option, radiofrequency may be the answer you’ve been waiting for.
In this article we explain what radiofrequency is, how it works and why it is a tool increasingly used in regenerative medicine and pain management.
What is radiofrequency?
Radiofrequency is a minimally invasive medical technique used to treat different types of chronic pain.
It is performed through a very fine needle guided by images (such as ultrasound or X-rays), a controlled electric current is applied on the nerves that transmit pain, blocking or modulating those signals.
This needle (or also called electrode) allows to reach the target to apply the RF treatment. Typically the electrode is coated with Teflon to isolate the device, except for the tip, which allows high current densities to be generated at the chosen point.
The device is equipped with a dispersion plate to collect the current applied to the target, in order to close the electrical circuit.
The result: less pain and more quality of life, without the need for surgery or long recovery periods.
What types of radiofrequency are there?
There are two main ways to apply this technique, and the choice depends on the type of pain and the patient:
Continuous radiofrequency
- It uses heat to “deactivate” in a controlled manner a nerve that is causing pain.
- It is usually applied in cases of well localized and persistent pain.
- Relief can last from 6 months to more than a year.
Pulsed radiofrequency
- It does not generate destructive heat, but modulates nerve activity through electrical pulses.
- Ideal for neuropathic or nerve pain, such as sciatica, radiculopathy or neuralgia.
- It has fewer risks and can be repeated several times.
Both options are performed in an office or minor operating room, and the patient walks out the same day.
Ways to apply radiofrequency
- RF monopolar. Where the needle tip would act as the active electrode, and the dispersion plate as the circuit closure.
- Bipolar RF. Two needles would act as electrodes, circulating the energy between the first (active pole) and the second (passive pole), so that the circuit is closed between them, not being necessary the presence of a dispersion plate. The morphology of the resulting electric field is concentrated between the active poles, creating, depending on factors such as the angulation of the needles and the characteristics of the surrounding tissues, larger areas. It is important to note that the temperature will be higher at the active pole, and lower at the passive pole, as the current loses intensity as it passes through the tissue (impedance).
What kind of pain can be treated with radiofrequency?
This treatment is very useful in conditions such as:
- Chronic low back and neck pain
- Joint pain (knee, hip, shoulder)
- Trigeminal neuralgia
- Nerve pain due to hernia or sciatica
- Post-surgical or difficult to manage pain
Benefits of radiofrequency for pain
- Outpatient procedure, without hospitalization
- Fast recovery (you resume your activities in a few days)
- Prolonged pain relief
- Reduces the use of painkillers or anti-inflammatory drugs
- Safe alternative if you do not want surgery
- Compatible with other regenerative treatments (PRP, ozone therapy, etc.)
Is it safe?
Yes, radiofrequency is considered a safe treatment with few side effects, especially when performed by experienced professionals. In our clinic, we use advanced imaging and nerve monitoring protocols to ensure precision and long-lasting results.
Is it for me?
If you have tried different pain treatments without results, or are simply looking for a modern and less invasive alternative, radiofrequency may help you. Medical evaluation is essential to determine if you are a good candidate.
