Radiofrequency Ablation (or RFA) is a minimally-invasive procedure that can provide lasting relief to those suffering from chronic pain. In the majority of patients, pain frequency and severity are reduced for one to two years. An electrical current produced by a radio wave is used to apply heat to particular nerve pathways to shut off the transmission of pain signals to the brain. RFA brings safe, effective relief from low back, neck, and joint pain and is covered by Medicare and most private insurances.
