Selective Nerve Root Injections
A selective nerve root injection (SNRB) is a minimally invasive medical procedure where a local anesthetic and a long-lasting steroid (cortisone) are injected directly around a specific spinal nerve root as it exits the spinal column. This procedure is used both diagnostically and for therapeutic relief.
Diagnostically, doctors use the local anesthetic to temporarily "numb" a specific nerve. If your radiating pain disappears or improves immediately, it confirms that the targeted nerve is causing your pain.
For therapeutic relief, the corticosteroid reduces swelling and inflammation around the irritated nerve root, breaking the pain cycle while underlying conditions heal.
