Selective nerve root blocks can bring relief from pain and help diagnose the primary site of low back or leg pain. A compressed nerve root can become inflamed and result in moderate to severe back and leg pain. MRI is normally used to find the source of the pain, but if the test does not definitely identify the site, a nerve root block can pinpoint the site and relieve the pain simultaneously. The block is also used for treating a disc that ruptures outside of the spinal column. Pain relief injections can be administered up to three times a year.
