Medial Branch Block (Lumbar)

This is an injection of numbing medicine. It bathes the medial branch nerves, which attach to the facet joints of your spine. These nerves hurt when facet joints are injured or diseased. The injection helps find the source of your pain.

When the procedure is finished, you may feel pain relief for the next few hours. You may be asked to keep track of your pain level as the medicine wears off. If the block was successful, your doctor can recommend a procedure to provide long-lasting relief.
