Selective Nerve Root Injections (SNRIs) are a minimally invasive procedure used to diagnose and treat nerve pain caused by compressed or irritated nerve roots in the spine. These nerve roots can become inflamed due to a variety of conditions such as herniated discs, spinal stenosis, or degenerative disc disease.
During the procedure, Dr Patterson will use imaging techniques such as X-ray to guide a needle to the specific nerve root requiring treatment. A mixture of local anesthetic and corticosteroid medication is then injected close to the nerve root, providing both immediate pain relief and longer-term reduction of inflammation.
SNRIs are considered a safe and effective treatment for nerve pain and are often used when other conservative treatments such as physical therapy or medication management have failed to provide relief. The procedure typically takes less than an hour to complete and can be done on a day case basis.
It is important to note that SNRIs are not a cure for nerve pain and may need to be repeated or used in conjunction with other treatments to manage chronic pain. As with any medical procedure, there are potential risks and complications associated with SNRIs, such as infection or nerve damage.
