I have heard of "facet joints" causing back pain. What is this?

Spine Joints. Facet joints are places on the spinal bones where two bones actually meet and articulate, therefore a facet joint injection is into that place where they meet. Many times arthritis or inflammation can arise here and cause pain. Epidural injections are also helpful to reduce inflammation into the spinal canal area or around the spinal nerve roots exiting the spine.
Yes. Facet joints, like any other weight bearing joint can be injured andor become arthritic creating back pain or grow larger or give off cysts called synovial cysts which can pinch nerves leading to sciatic symptoms.
Injections help. Facet joint injections is an injection used to determine if the facet joints are the source of pain. These injections can also provide pain relief.
