Radiofrequency used to heat up and destroy the offending nerve tissue hasn't been all that successful either. Studies just don't show the positive long-term benefits needed.
More recently, scientists are studying the effects of pulsed radiofrequency (PRF). Short-lasting pulses of electrical currents are delivered to the nerve. The current used is high enough voltage to reach the radiofrequency range but not high enough to destroy tissue.
Short-term results are promising but not refined enough to recommend for everyone. For now, pain management from a multidisciplinary approach remains the gold standard for this type of problem.
Learning to manage the symptoms while increasing activity and function are the main goals. A combined effort of physical therapy, behavioral counseling, drugs, and alternative medicine help many people while waiting for a better approach.
