Radiofrequency ablation, or RFA, is one of the most popular minimally invasive techniques used to treat chronic pain disorders.
The physician uses x-ray guidance (fluoroscopy) to direct the RFA needle toward the medial or lateral branch nerves. Medial branch nerves transmit pain from the facet joint(s). Each facet joint is connected to 2 medial branch nerves that carry pain signals away from the spine to the brain.
It’s not uncommon to feel some discomfort, superficial burning pain, or hypersensitivity in the area of the procedure. Some patients describe the feeling as similar to a sunburn. On average, this pain lasts no longer than 1 to 2 weeks after the procedure.
