Medial Branch Block is a diagnostic procedure that allows us to source the origin of your back pain. Medial Branch Nerves come from the spinal cord and innervate the zygapophyseal joints. A treatment plan can be created in case numbing this nerve relieves pain. The next step would be to perform a Radiofrequency Ablation, which is the cauterization of the Medial Branch Nerves that provides a relief that actually is long-lasting.
