Radiofrequency Neurolysis (Rhizolysis)

Radiofrequency (RF) Neurolysis utilizes heat to disable selected nerve fibers to effectively block pain signals to the brain, which can reduce or eliminate various types of pain, particularly neck and back pain.

During this minimally invasive procedure, a needle is used to insert a small electrode that uses a radiofrequency current to heat up and and disable the involved nerve. RFN is often prescribed after intermittent anesthetic injections fail to provide adequate or extended pain relief. Patients often experience significant and rapid reduction or elimination of pain from the RF treatment. Proven safe and effective as a treatment for some forms of chronic pain, patients undergoing RF treatments experience pain relief that can last six to 12 months and in some cases, even longer.

How long before I feel relief from radiofrequency treatment? How long does it last?

Radiofrequency procedures take just 15-45 minutes from start to finish, and patients often experience relief once the procedure-related inflammation subsides.  It takes from 3 to 7 days for the post-procedure inflammation to subside.  The pain relief from a radiofrequency procedure can last from 6 to 18 months.
