Facet Joint Pain

The two are easily confused: facet joint pain is hard to tell apart from pain coming from other structures in the lower back ¹.

Facet joint pain is back-dominant. Disc problems and nerve-root irritation are more often leg-dominant, with a recognisable band of numbness or pins and needles, sometimes real weakness. If your pain travels past the knee, a non-facet cause is more likely ¹, the pattern covered on our sciatica and lumbar disc bulge pages.

Neither a scan nor a hands-on test can prove facet joint pain. Clinical examination "has not been proven to objectify" it, Kemp's test has limited value for ruling it out, and tenderness over the joints correlates only poorly with who responds to facet treatment ¹. CT and MRI findings correlate weakly with pain and mainly serve to rule out red flags ¹, and some studies found no association at all between facet arthritis on CT and low back pain ⁵. Scan reports often mention changes that reflect the normal passage of time, not damage ².

So a facet diagnosis is a working conclusion drawn from your pattern, your movement and how you respond to treatment, not something a scan settles.

Most people with this pattern don't need a scan to get started. Your clinician asks when the pain began, where it sits, what eases it or sets it off, and whether you've had tingling, numbness or pain in your legs ². Then comes the examination. With facet joint pain, leg strength and reflexes are normal, and the straight leg raise, a test that stretches the nerves running into your leg, is usually negative ¹.

The nearest thing to a confirming test is a diagnostic nerve block, where a doctor numbs the small nerves supplying the joint to see whether the pain goes. Even that gives a false positive in 25 to 40% of cases, so some guidelines ask for two separate blocks, each giving at least 80% pain relief ¹.

The first job is working out whether this is actually a facet pattern, and what in your week is loading those joints. How you're moving is more changeable than what your scan shows.

How strong is the evidence? A 2021 Cochrane review found physiotherapy produced improvement in the short and intermediate term, with long-term results inconclusive ¹. Graded stabilising exercise improved disability and self-efficacy more than simply being told to walk daily, but not pain over the longer term ⁴. And the finding that matters most: adding radiofrequency denervation to a standardised exercise programme produced no clinically important improvement over the exercise programme alone ⁵. That's the strongest argument there is for leading with structured exercise, which isn't the same as saying exercise is guaranteed.

Facet joint pain usually comes from a worn, irritable joint, not an injury that heals on a clock ¹. On The Well Motion Recovery Path™ you move up a phase when your back copes with more, not when a date arrives.

• Reset: while it is irritable. Less sustained arching and twisting ⁵, regular walking ^1,2, heat if it helps ², and manual therapy alongside your first low-load control exercises ¹. Expect morning stiffness to outlast the sharp catches. We move you on once everyday movement no longer builds the pain.
• Rebuild: the longest phase. Graded strengthening through our exercise prescription and conditioning work, from control into fuller loading ^1,4. Expect the odd flare as the load goes up, which means adjust, not stop. We move you on when your back does what your daily tasks ask of it.
• Return: the standing, lifting, work or sport that used to set it off, tested at the length and load you need. You leave with a progressive walking plan, because walking with education delayed the next episode in an Australian low back pain trial ⁷.

How long it usually takes. No study gives a recovery time for facet joint pain itself. In one small trial of 39 people, all of whom had already had radiofrequency denervation, a six-week stabilisation exercise programme added benefit over education alone ¹⁰. Pain lasting past about twelve weeks is classed as chronic ² and needs a broader plan.

No trial has tested prevention for facet joint pain on its own. The trials are in low back pain generally, and this is what they found:

• Keep exercising once it settles. Across 21 trials, exercise combined with education cut the risk of a new episode of low back pain by about 45%. Exercise on its own helped too, on weaker evidence ⁶.
• Walk, and build it up. An Australian trial followed 701 adults who had just got over an episode of low back pain. Half were given a progressive walking programme and six physio sessions over six months. Their next activity-limiting episode typically came 208 days later, against 112 days in the group given nothing ⁷.
• Don't count on a belt or insoles. In the same review, back belts and shoe insoles didn't prevent low back pain, and education without exercise didn't either ⁶.
• Look at weight and smoking. Keeping to a healthy weight helps, and smoking is associated with low back pain ².
