The small joints along the spine are a common, under-recognized source of back and neck pain — and one of the few with a true diagnostic test.
Every spinal level has a pair of facet joints — small, cartilage-lined joints that guide motion. Like any joint they can become arthritic or irritated, producing aching pain near the spine that worsens with extension and rotation. X-rays and MRI show arthritis in almost everyone past middle age, which is exactly why imaging alone can't make this diagnosis.
The honest answer: no exam maneuver or scan proves a facet joint is the pain source. The accepted test is a medial branch block — numbing the small nerves that carry the joint's pain signal and seeing whether your pain drops substantially while the anesthetic works. Meaningful relief, ideally on two separate occasions, makes the diagnosis.
If any of these apply, go to an emergency department or call 911 rather than waiting for a clinic appointment.
Core strengthening, extension-tolerance work in therapy, activity adjustment, and time are the foundation. Many flares settle in weeks and never need a needle.
When blocks confirm the facet joints, radiofrequency ablation can quiet the pain signal for a year or more, and can be repeated. A facet joint injection is sometimes used for a targeted flare. The sequence matters: diagnosis by block first, treatment second.
Facet pain by itself is rarely a surgical problem. Surgery enters the conversation when facet arthritis is part of a bigger picture — instability, deformity, or stenosis with its own symptoms. If your imaging and story point that way, we'll say so and refer.
