RF / PRF
RF means radiofrequency. PRF means pulsed radiofrequency. Both deliver energy through a needle placed at the nerve that is carrying the pain signal. Dr. Nitish Mandal uses them for selected severe nerve pain, including neck pain and cervical spondylosis, after a diagnostic block has confirmed the target.
What does RF / PRF stand for?
Radiofrequency (RF) and pulsed radiofrequency (PRF) are used for severe nerve pain. Heat or pulsed energy is delivered through a needle placed at the nerve that is carrying the pain signal.
Neck pain and spondylitis pages also mention radiofrequency ablation and medial branch blocks, which target the small joints of the neck.
When is RF / PRF discussed?
- Severe nerve pain that has not settled with tablets.
- Neck pain and cervical spondylosis after examination.
- Pain that follows a nerve path, not only a sore muscle.
Why is a diagnostic block done first?
A medial branch block or another diagnostic step may come first, so the nerve being treated is the one that actually produces your pain.
The motto of the practice is Minimum Medicines, Maximum Relief. RF / PRF is one way to treat the nerve rather than only raising tablet doses.
Is radiofrequency surgery?
- The nerve or joint is identified on examination and, when needed, a diagnostic block.
- A needle is placed with guidance. RF or PRF is delivered at that target.
- You are typically able to go home the same day.
Frequently asked questions
- What does RF / PRF stand for?
- Radiofrequency and pulsed radiofrequency. They are used for severe nerve pain, including neck pain and spondylitis.
- Is this surgery?
- No. It is a clinic procedure with a needle placed at the nerve or joint, not an open operation.
- Will I still need tablets?
- The aim is fewer medicines where possible. Some people still need a simple tablet plan afterwards. That is decided in clinic.
- RF vs PRF: what is the difference?
- RF uses heat at the nerve. PRF uses pulsed energy. Which one is used depends on the nerve and the diagnosis. That choice is made in clinic.
RF / PRF is for selected severe nerve pain, not for every stiff neck. The first visit is to find the nerve, then decide whether this procedure belongs in the plan.
