What are facet joints?
Facet joints are located on the back of the spine on each side where one vertebra slightly overlaps the adjacent vertebrae. They guide and allow the complicated movements of the spine.
What is facet joint syndromE?
Facet joint syndrome involves a constellation of symptoms resulting in diffuse pains that do not fit a clear nerve root pattern. These pains are typically worsened with cold damp weather and movement of the spine, such as standing, walking, and turning in bed.
Why inject the facet joints?
Facet injection is performed to help diagnose and/or treat pain related to disease or injury of the posterior joints of the spine. Injection of these joints is an accurate and definitive way to diagnose facet joint pain syndrome because certain joints may appear abnormal but not cause pain and, conversely, the problem joints may appear nearly normal.
When will the pain relief take effect?
You may experience numbness and/or relief from your spine pain for up to 6 hours after the injection. This is due to the long-acting anesthetic that was injected. Your usual symptoms may then return and may possibly be worse than usual for a day or two. The beneficial effects of the steroid injected usually require 2 to 3 days to begin and it may take as long as a week.
