03 Aug Feeling Worse After a Spinal Injection? Here’s What’s Actually Normal

Up to 18% of patients report increased pain for a few days after a cervical epidural injection, according to research published in 2022, and for most people that flare settles within 48 hours. If you had a spinal injection this week in Broken Arrow, Oklahoma and you are hurting more today than you did before the needle, you are not alone, and in most cases this does not mean the procedure failed. Knowing whether it’s normal to feel worse after a spinal injection, and knowing when it’s not, is the difference between riding out a predictable flare and catching a real problem early.

Why Pain Can Spike Before It Improves

A spinal injection introduces fluid into a small, already irritated space around the spinal nerves. That fluid has to go somewhere, and the needle itself passes close to tissue that was already inflamed. The result is a temporary mechanical irritation that has nothing to do with whether the steroid will eventually work. The full effect of the anti-inflammatory medication typically takes up to two weeks, so a rough first 48 to 72 hours is common even in injections that go on to work well.

Positioning during the procedure and age appear to play a role in how much soreness shows up afterward, according to a 2021 study on post-injection pain. Some patients feel a flare that peaks the day after the injection and fades by day three. Others notice almost nothing at all. Both patterns are considered typical.

The Normal Recovery Timeline for a Spinal Injection

Timeframe	What’s Typical
First few hours	Numbness or tingling from local anesthetic, mild soreness at the injection site
Day 1 to 3	Pain may temporarily worsen before the steroid takes effect
Day 3 to 5	Steroid begins reducing inflammation for most patients
Up to 2 weeks	Full effect of the medication, pain relief peaks

As the table shows, a rough first three days followed by steady improvement is the expected pattern, not a sign the injection didn’t take.

Signs That Are Not Normal

Contact your provider right away if you develop severe pain, fever above 100 degrees, new numbness or weakness in your legs, redness or swelling at the injection site, or loss of bladder or bowel control. Those symptoms fall outside the expected flare and need same-day evaluation. See epidural injection guidance from MedlinePlus for a full overview of the procedure and recovery.

Why Choose Pain Management of Oklahoma

A predictable flare after a spinal injection still needs someone watching for the signs that separate normal soreness from a real complication, and our team walks every Broken Arrow patient through exactly what to expect before they leave the building, not after they’ve already called in a panic. We give you a written pain scale to track day by day so you and your provider have real data instead of a vague “it still hurts” at your follow-up. When a flare runs longer than the typical window, we adjust the plan instead of just telling you to wait it out, whether that means a follow-up injection, a change in medication, or a referral to physical therapy. This approach is grounded in research on spinal injection outcomes, not guesswork. If you’re still working through your options, learn more about our injection services or read about how radiofrequency ablation compares for longer-term relief, or contact our team directly.

Frequently Asked Questions

How long does it take for a spinal injection to work?

Most patients notice the steroid’s effect within three to five days, with the full benefit developing over about two weeks. Pain relief can last for weeks to months depending on the underlying condition.

Why does my back hurt more the day after my epidural?

The needle and fluid temporarily irritate tissue that was already inflamed, and the anesthetic wearing off can unmask soreness that was numbed during the procedure itself. This typically resolves within 48 hours.

Is it normal to have a headache after a spinal injection?

A mild headache can happen, but a severe headache that worsens when sitting up may signal a spinal fluid leak and should be reported to your provider promptly.

How many spinal injections can I safely have in a year?

Many providers limit steroid injections to three or four per year in the same area to reduce the risk of tissue and bone effects from repeated steroid exposure, though this varies by patient and injection type. For post-procedure comfort, see this post-op tips guide.

When should I go to the ER after a spinal injection?

Go immediately if you develop a fever, new leg weakness, loss of bladder or bowel control, or a rapidly spreading area of redness and warmth at the injection site.
