Facet joints are a series of small joints at the back of your spine that help guide the motion of your spine.

Sacroiliac joints are 2 large joints at the back of your pelvis.

Both facet and sacroiliac joints can become painful when injury, metabolic conditions or wear and tear damage them. Joint injections can be useful to:

1. Identify which joints are causing your pain.

2. Providing treatment to the painful joints.
