Selective Nerve Root Block (SNRB) is a minimally invasive procedure used to diagnose and treat pain caused by nerve root irritation or inflammation in the spinal column. Nerve root irritation or inflammation can occur due to conditions such as herniated discs, spinal stenosis, or degenerative disc disease.
During the procedure, a local anesthetic and/or anti-inflammatory medication is injected around the nerve root that is causing pain. This injection can help reduce inflammation and relieve pain. If the patient experiences significant pain relief after the injection, it confirms that the pain is originating from the nerve root.
SNRB is typically used to treat chronic back or leg pain caused by nerve root irritation or inflammation. It is a minimally invasive procedure that can be performed on an outpatient basis and has few side effects. The effects of the injection can last for a few weeks to several months, depending on the individual and their condition. If the pain relief is significant, additional treatments such as physical therapy, chiropractic treatment, or medication management may be recommended to manage the underlying condition causing the nerve root irritation.« Back to Glossary Index
