For most people, facet joint injection recovery is short and uneventful: you rest for the remainder of the day, you may feel sore for a day or two, and the real benefit from the steroid arrives gradually over the following days to weeks. The numbing medicine wears off within hours, so the relief you feel in the first afternoon is not a reliable preview of how the injection will work. This guide walks through each stage, what is normal, what is not, and how long the effect can last, so you know what you are looking at when you are lying on the couch that evening.
TL;DR
- The numbing medicine helps for a few hours. The steroid usually begins working after 2 to 5 days, and its full effect can take 2 to 3 weeks.
- A temporary pain flare in the first 24 hours is possible. Cold packs are the usual first step.
- Significant complications are uncommon, and minor soreness at the injection site typically settles within about 48 hours.
- How long relief lasts varies from person to person. The injection is meant to open a window for rehabilitation, not to replace it.
- Call the clinic promptly for fever, spreading redness, new weakness or numbness that does not clear, or pain that keeps getting worse.

What a facet joint injection is meant to do
Facet joints are the small paired joints along the back of the spine, in the neck, mid-back, and lower back. When one becomes inflamed or arthritic, it can cause localized pain that often worsens with extension, twisting, or standing for long periods. During a facet joint injection, medicine is placed into the inflamed joint or around it to reduce inflammation and ease pain.
That purpose shapes recovery. The injection has two jobs. The first is diagnostic: if the pain drops while the joint is numb, that joint is likely a pain source. The second is therapeutic: the steroid calms inflammation so you can move, strengthen, and retrain the area. Understanding both jobs explains why the first few hours matter and why the following weeks matter even more.
If you want a closer look at the procedure itself, including who is a candidate, see our page on facet joint injections.
The first hour: the part many patients do not expect
The period right after the injection is partly diagnostic. According to the University of Michigan’s PainGuide, clinicians may ask you to perform the movements that normally trigger your pain, to judge whether the joint that was injected was truly the source. Many patients assume they should simply go home and rest. In practice, the more honestly you test your usual painful movements while the area is numb, the more useful the information is for planning your next step.
Pay attention to specifics and, if possible, keep notes:
- Which movements normally hurt, and how much did they hurt this time, on a 0 to 10 scale?
- Did the pain drop partly or completely?
- How many hours did the relief last before the old pain returned?
These notes are often the most valuable thing you bring to a follow-up visit. A vague “it helped a bit” is hard to act on. “It dropped from a 7 to a 2 for about five hours, then crept back” tells us a great deal.
Why you should arrange a ride home
The numbing medicine can make the area feel heavy or strange, and in a small number of cases it can affect nearby nerves. The clinical literature describes situations in which contrast dye leaks into the epidural space, often because the joint capsule ruptures, which can cause temporary weakness in the legs. It is managed clinically and resolves, but it is unsettling if no one has told you it can happen. Have someone drive you home, and do not plan anything demanding for the rest of the day.
One related point: for these procedures, many clinicians prefer that you are awake and able to report what you feel during needle placement. Heavy sedation can blur the very feedback that confirms the right joint is being treated, so ask your physician beforehand what to expect.
The first 24 hours
The anesthetic effect is immediate but brief. The VA’s patient library notes that relief from the numbing medicine lasts only a few hours, while the steroid has not yet started working. This gap is where many people get worried. You might feel great at 3 p.m. and sore at 9 p.m. That is the anesthetic wearing off, not a failed injection.
Soreness and pain flares
A temporary increase in your usual pain during the first day can happen. The same VA material describes pain flares in the first 24 hours, and suggests cold packs for 10 to 15 minutes, one to four times a day. The University of Washington’s after-injection handout also recommends a cold pack for pain on the day of the injection, and notes that a bag of frozen peas works well. Wrap whatever you use in a thin towel so it does not sit directly on the skin.
Most minor side effects, such as soreness or swelling around the needle site, are self-limiting and typically resolve within 48 hours.
What to do that day
- Rest for the remainder of the day, but do not stay completely still. Short, gentle walks around the house are fine unless your physician told you otherwise.
- Use cold, not heat, over the injection site on the day of the procedure.
- Follow your discharge instructions about bandages and bathing. Different clinics have slightly different rules.
- Skip strenuous exercise, heavy lifting, and long drives until you have been cleared.
- If you take medications for diabetes, check your glucose more often than usual. Steroids can temporarily raise blood sugar, and your prescriber can tell you how closely to watch it and for how long.
Days 2 to 7: when the steroid begins to work
The anti-inflammatory effect of the steroid typically takes 2 to 5 days to begin. This is the stretch where patients most often ask whether the injection worked. The honest answer is that you cannot judge it yet. Some people notice gradual improvement on day three. Others feel nothing until the end of the first week.
During this period, most people can return to their usual routine at a gentler pace. Desk work is typically manageable. Anything involving repeated bending, twisting, or heavy loads is better delayed until your pain pattern is clearer. If your job is physical, talk with your physician about a graded return rather than guessing.
This is also the best time to begin the foundational work that makes the injection worthwhile. Gentle walking, posture changes, and the early stages of a home program can usually start. Our posts on lower back pain and posture and exercises for lower back pain are reasonable starting points, but follow whatever your treating physician or therapist has specifically told you.
Weeks 2 to 3: the full effect
The full therapeutic benefit of a steroid injection is often not reached for 2 to 3 weeks. That is the point at which it makes sense to evaluate the result. Compare your pain, your range of motion, and what you can do in a normal day, not just a single pain score.
A useful framework is to ask three questions at your follow-up:
- Is my pain lower than before the injection, and by how much?
- Can I do things I had stopped doing, such as standing through a meeting, walking the dog, or sleeping on my back?
- Is the benefit holding steady, or already fading?
The answers guide the next step, whether that is more rehabilitation, a repeat injection, or a different treatment.
Recovery timeline at a glance
| Time after injection | What is typical | What to do |
|---|---|---|
| First hours | Numbing medicine gives temporary relief; area may feel heavy | Test your usual painful movements as directed and note the result; have a driver |
| Hours 6 to 24 | Anesthetic fades; soreness or a short flare is possible | Cold pack 10 to 15 minutes, rest, gentle walking |
| Up to 48 hours | Minor soreness or swelling at the needle site settles | Avoid strenuous activity |
| Days 2 to 5 | Steroid begins to reduce inflammation | Resume normal routine gradually, start gentle movement |
| Weeks 2 to 3 | Full steroid effect expected | Assess results and plan rehabilitation |
These ranges describe typical courses, not promises. Individual responses differ.
What is normal and what is not
Serious problems are uncommon. In a large study covering more than 43,000 facet joint injections, significant adverse events were reported in fewer than 1% of patients. The University of Michigan lists the infrequent risks as allergic reaction to medication, nerve damage, and bleeding or bruising at the injection site. Bleeding risk is generally classified as low for facet injections, though your physician will still review any blood thinners you take.
Contact the clinic the same day, or seek urgent care if you cannot reach us, if you notice any of the following:
- Fever, chills, or redness and warmth that spreads from the injection site
- New weakness, numbness, or tingling in an arm or leg that does not fade as the anesthetic wears off
- Loss of bladder or bowel control, which is an emergency
- Severe or steadily worsening pain, different from your usual pain
- Signs of an allergic reaction, such as hives, facial swelling, or trouble breathing

A note on other health factors
Recovery does not happen in isolation. Blood sugar control, body weight, and medication choices all interact with how your joints feel. If you are on a medically supervised weight-management program, it can be worth understanding how GLP-1 medications relate to joint inflammation and then discussing it with the physician who manages both. Tell every prescriber involved that you recently had a steroid injection.
How long do facet joint injections last?
This is the question patients ask most, and the answer is unsatisfying but true: it varies. The StatPearls review advises that clinicians should tell patients that pain relief with a facet joint injection is variable and that repeated injections may be needed. Some people get weeks of relief, some get several months, and some get little.
In our experience, many patients come in after trying several treatments, and they often expect a single injection to be a cure. We prefer to frame it differently. A good response means your pain has dropped enough that you can do the exercise and movement retraining that address why the joint became irritated in the first place.
Several factors influence how long the effect holds:
- How much of your pain comes from the facet joint. If other sources contribute, such as discs, the sacroiliac joint, or muscle, the injection can only address part of the picture. Our page on sacroiliac joint steroid injections explains one common overlap.
- The degree of joint degeneration. More advanced arthritis tends to be harder to settle for long.
- What you do afterward. Clinical research on facet joint disorders describes how lasting relief depends on maintaining good alignment, which means self-directed stretching and strengthening of the supporting muscles to prevent symptoms from returning.
- Daily load. Prolonged sitting, repetitive twisting, and poor workstation setup can keep irritating the joint.
Why rehabilitation is part of recovery, not an add-on
Consensus guidelines on lumbar facet joint pain recommend a trial of at least 3 months of conservative treatment, including exercise and physical therapy, before moving to facet joint interventions. The same logic applies afterward: the injection is intended to supplement a rehabilitation program, not replace one.
A practical post-injection plan often looks like this:
- Weeks 1 to 2: walking, gentle mobility work, and posture awareness.
- Weeks 2 to 6: progressive core and hip strengthening, with attention to the movement patterns that provoked your pain.
- Beyond six weeks: a maintenance routine you can sustain without supervision.
If you want structure, our physical therapy program is built around this window. For self-guided support, see our post on yoga for lower back pain and our daily spine health tips, and check with your physician that any given routine suits your condition.
Our perspective on recovery
We tend to describe a facet joint injection to patients as a way to buy a quiet window. The pain settles, the inflammation eases, and for a period you can move without the joint fighting you. What you do with that window decides much of the outcome.
We see a recurring pattern. Patients who treat the injection as the whole plan often return when the effect fades, discouraged. Patients who use the first few weeks to restart walking, strengthen their trunk and hips, and fix the habits that overloaded the joint tend to have a better sense of what the injection actually did for them. We also take a conservative view of repetition: if an injection gives a clear but short benefit, that is useful information, and it should prompt a conversation about the underlying cause, not an automatic repeat.
We also prefer to set expectations before the procedure, not after. You should know that the numbness is temporary, that the steroid takes days to act, that a flare is possible, and that the result is not guaranteed. A calm patient who knows the timeline recovers better than an anxious one watching the clock.

When an injection is not enough
Sometimes facet joint injections give only brief relief, or the pain turns out to come from elsewhere. In that case, the conversation shifts to other non-surgical options. Depending on your diagnosis, these can include back pain therapy, radiofrequency procedures aimed at the nerves that carry joint pain, or regenerative medicine approaches such as PRP therapy. Which of these makes sense depends on your imaging, your exam, and how you responded to the first injection, so it is a decision for an in-person evaluation, not a general rule.

FAQ
How long does it take to recover from a facet joint injection?
Most people feel back to normal activity within a day or two, with minor soreness at the injection site that typically resolves within about 48 hours. The benefit from the steroid is a separate timeline: it usually starts after 2 to 5 days and can take 2 to 3 weeks to reach its full effect.
Why does my pain feel worse right after the injection wears off?
The numbing medicine lasts only a few hours, and the steroid has not started working yet. Your usual pain can return, or flare briefly, during that gap. A cold pack for 10 to 15 minutes, one to four times a day, is the usual first step, and a flare that keeps escalating should be reported to your clinic.
How long do facet joint injections last?
Relief is variable. Some people have weeks of benefit, some several months, and some very little. Your physician cannot promise a duration, but your response to the first injection, and how well you follow up with exercise and physical therapy, helps guide what comes next.
Can I exercise after a facet joint injection?
Gentle walking is generally fine, but avoid strenuous exercise and heavy lifting on the day of the procedure. Many patients can progress to strengthening over the following weeks, ideally with guidance from a physical therapist, and your own physician should confirm the pace.
Do facet joint injections affect blood sugar?
The steroid can temporarily raise blood glucose. If you have diabetes, tell your physician before the procedure and ask how closely to monitor your levels afterward and when to call your prescriber.
