There are a multitude of chronic pain conditions that respond well to this treatment. Chronic spinal pain, including spinal arthritis (spondylosis), post-traumatic pain (whiplash), pain after spine surgery, and other spinal pain conditions are those most commonly treated with RFL. Other conditions that are known to respond well to RFL include some neuropathic pain conditions like Complex Regional Pain Syndrome (CRPS or RSD), peripheral nerve entrapment syndromes, and other assorted chronic pain conditions. A patient’s candidacy for RFL is usually determined by the performance of a Diagnostic Nerve Block. This procedure will help to confirm whether a patient’s pain improves just for the duration of the local anesthetic (or not). Patients who have little to no pain relief after a diagnostic nerve block are not candidates for a neurodestructive procedure like RF Lesioning.
