A Selective Nerve Root Block is a minimally invasive procedure designed to diagnose and relieve nerve pain at its source. This treatment targets a specific spinal nerve root that may be irritated or compressed, often due to conditions such as herniated discs, spinal stenosis, or bone spurs. When a nerve root becomes inflamed, it can cause pain, numbness, tingling, or weakness that radiates from the spine into the arms or legs. By delivering medication directly to the affected area, a selective nerve root block can reduce inflammation, relieve pain, and help confirm which nerve is causing the symptoms.
During the procedure, a doctor uses fluoroscopic (X-ray) guidance to accurately position a thin needle near the targeted nerve root. A small amount of contrast dye ensures precise placement, followed by an injection of a local anesthetic and anti-inflammatory medication. Patients typically remain awake but comfortable throughout the process, and the procedure usually takes only a few minutes. Many people experience immediate pain relief from the anesthetic, followed by longer-lasting relief as the steroid reduces inflammation over time.
Selective nerve root blocks serve both diagnostic and therapeutic purposes. If the injection relieves pain, it helps confirm the exact source of nerve irritation, which is valuable for planning future treatments. For some patients, the injection alone provides significant pain reduction that lasts weeks or even months. At our clinic, we use SNRBs as part of a comprehensive pain management plan tailored to each patient’s condition and goals. This targeted approach helps patients regain mobility, improve daily function, and avoid more invasive procedures when possible.
