What is a facet joint injection?

Facet joint injections are used for treating back pain and to help determine whether the facet joint is a source of the pain being experienced.

Facet joint injections (also referred to as facet blocks) consist of injections of local anesthetics and steroids into the facet joint of the spine. Or simply, injections used to alleviate the symptoms of facet joint syndrome.

Causes of facet joint pain

Since the syndrome involves immense back pain due to facet joints, the causes vary a lot. Some of these include:

  • Arthritis
  • Degenerative diseases of the spine
  • Trauma


Symptoms of painful facet joints in the lumbar spine (Lumbar Facet Syndrome) include lower back pain and pain in the buttocks, thighs, groin, and hips.

Symptoms of cervical facet syndrome which involves painful facet joints in the cervical spine include shoulder pain, neck pain, upper back pain, and headaches. Other conditions for this may be a dipsogenic pain, Sacroiliac Joint (SI Joint) pain, and Myofascial Pain.


The procedure typically takes 15–20 minutes, and uses a local anesthetic.
