Facet joint injections are a minimally invasive procedure used to diagnose and treat pain originating from the small joints in the spine known as facet joints. These joints play a key role in providing stability and flexibility, but can become inflamed due to aging, arthritis, or injury. The procedure involves injecting a combination of a local anesthetic and a corticosteroid directly into or near the affected joint to reduce inflammation and block pain signals. Facet joint injections not only provide effective pain relief but also help physicians accurately identify the source of discomfort, making them an important tool in comprehensive spine care and pain management.
