Facet Joint Injection: Recovery Time, Results and Next Steps
Facet joint injections are used to diagnose and treat pain coming from the small joints of the spine. Here is what recovery looks like, how long relief lasts, and what to do if the injection does not work.

|---|---|---|---|---|---|
| C1 | Facet joint injections place anesthetic, often with corticosteroid, into or around a spinal facet joint under image guidance. | low | supported | V1 | Technique is standard and image guidance is expected. |
| C2 | A key purpose is diagnostic: the response identifies whether facet joints are the pain source and whether radiofrequency ablation is likely to help. | medium | supported | V1, V2 | Diagnostic value is better established than long-term therapeutic value. |
| C3 | Signs of infection after injection, including fever, spreading redness, or escalating pain, need urgent medical review. | high | supported | V1 | Infection is rare but time critical. |
What a facet joint injection is for
Facet joints are the small paired joints at the back of each spinal segment. When they become arthritic or inflamed, they produce axial neck or low back pain that worsens with extension, twisting, and standing. A facet joint injection places local anesthetic — often with a corticosteroid — into or around the joint under fluoroscopic guidance [V1]. It serves two purposes: short-term pain relief, and confirming whether the facet joints are actually the source of pain.
Key numbers
- Hours: duration of the anesthetic phase, which is the diagnostic signal [V1].
- 2–7 days: onset of corticosteroid effect, when it occurs.
- Weeks to months: typical duration of therapeutic relief.
- 24–48 hours: usual restriction on heavy lifting and strenuous exercise.
Intra-articular injection vs medial branch block
| Procedure | Target | Main role |
|---|---|---|
| Intra-articular facet injection | Inside the joint capsule | Treat inflammation in a specific joint |
| Medial branch block | The nerves supplying the joint | Diagnose facet-mediated pain before ablation |
If a medial branch block gives strong, temporary relief that matches the anesthetic duration, radiofrequency ablation of those nerves becomes a reasonable next step for longer relief [V1][V2].
What the day looks like
You lie prone, the skin is cleaned and numbed, and the physician advances a fine needle to the target under X-ray guidance, confirming position with contrast. Each level takes only a few minutes. You are observed briefly, then discharged — with a driver if sedation was used. Keep a simple pain score log at 30 minutes, 2 hours, 8 hours, day 3, and week 2. That log is the most valuable output of the procedure.
Recovery, hour by hour
- 0–4 hours: numbness and often marked relief from the anesthetic.
- 4–24 hours: relief may fade; a soreness flare is normal.
- Days 1–3: local tenderness settles; resume walking and gentle mobility.
- Days 2–7: steroid effect appears if the joint was inflamed.
- Week 2 onward: use any relief window to progress strengthening [S1].
Risks
Most side effects are minor: soreness, bruising, transient pain flare, facial flushing, and short-term blood-sugar elevation in people with diabetes. Rare but important risks include infection, bleeding, allergic reaction to contrast or medication, and nerve irritation [V1]. Anticoagulants, active infection, uncontrolled diabetes, and pregnancy require specific planning.
Making the result count
A facet injection is a step in a plan, not the plan. Whether the response is good or poor, the next action should be defined in advance: progress rehabilitation, move to medial branch blocks and ablation, or reconsider the diagnosis.

Frequently asked questions
What is the recovery time for facet joint injections?
Most people go home within an hour and resume light activity the same day. Injection-site soreness typically lasts one to three days, and many clinicians advise avoiding heavy lifting or strenuous exercise for 24 to 48 hours. Steroid benefit, if it occurs, appears within 2 to 7 days.
What to expect after facet joint injections?
Expect a few hours of numbness from the local anesthetic, then a possible return of pain before the steroid takes effect. A short pain flare, mild bruising, and stiffness are common. Keep a pain diary for the first 8 hours and the first week, because that record guides the next decision.
What next if facet joint injections don’t work?
No response suggests the facet joints are not the main pain source. Next steps usually include re-examining the diagnosis, considering discogenic or sacroiliac pain, imaging review if red flags exist, and continuing graded exercise. Repeating an ineffective injection is rarely useful.
How long do facet joint injections last?
When they help, relief commonly lasts from a few weeks to a few months. Diagnostic blocks with anesthetic alone last only hours by design. Durable relief for facet-mediated pain more often comes from medial branch radiofrequency ablation.
What are the signs of infection after a facet joint injection?
Fever or chills, spreading redness or warmth at the site, drainage, escalating rather than settling pain, or new neurological symptoms such as weakness. These warrant same-day medical assessment. Infection after image-guided spinal injection is rare but serious.
