Spinal injections do hurt, but for most people the pain is moderate and brief. In a randomized trial measuring pain during epidural steroid injections, patients who received only standard local anesthesia rated their discomfort at roughly 5 out of 10 on average, and the worst of it lasted only seconds rather than minutes. The fuller picture involves what happens before, during, and after the needle goes in, and the surprisingly wide range of options available to make the experience more tolerable.
What the Procedure Feels Like, Step by Step
The term “spinal injection” covers several different procedures, but the general sequence is similar. You lie on your stomach or on your side, sometimes sitting up and leaning forward. The skin over the injection site is cleaned and then numbed with a local anesthetic, which itself involves a small needle prick and a brief burning sensation as the numbing agent spreads. This surface-level shot is typically described as the sharpest part of the whole procedure.
Once the skin and superficial tissue are numb, the physician advances a longer, thinner needle toward the target, whether that is the epidural space around the spinal cord, a facet joint along the spine, or the opening where a nerve root exits the vertebral column. You may feel pressure, a deep ache, or a momentary electrical-type zing if the needle brushes near a nerve. The actual delivery of medication, usually a corticosteroid mixed with an anesthetic, can produce a sensation of fullness or mild pressure in the back. The entire needle-in, medication-delivered, needle-out sequence often takes under a minute once the physician has positioned the needle, though the overall appointment including prep and imaging can take 15 to 30 minutes.
Physicians sometimes use a technique called a pre-injection block, where they numb deeper tissue layers before the main injection. In a series of 123 patients who received this approach, the deeper needling and infiltration of tender or painful areas was performed without pain because the sensory input from the target tissue was already blocked.1Journal of Back and Musculoskeletal Rehabilitation. Injection techniques in the management of local pain Not every clinic uses pre-injection blocks as a matter of course, so if you are particularly anxious, it is worth asking whether your provider offers this extra numbing step.
Putting a Number on the Pain
Pain is subjective, and individual accounts of spinal injections range from “barely noticed it” to “worst five seconds of my life.” Controlled studies give a more consistent picture. In a randomized trial comparing different comfort strategies during epidural steroid injections, the control group, which received only standard local anesthetic, reported an average pain score of about 5.2 on a 0-to-10 scale. Patients who received sedation averaged about 3.2, and those who used a virtual reality headset during the procedure averaged about 3.7.2The Lancet Regional Health – Southeast Asia. Virtual reality compared to sedation and standard local anesthetic for pain and anxiety during epidural steroid injections So even without any extra intervention beyond the local numbing, a score around 5 suggests discomfort but not agony for the typical patient.
Needle characteristics also influence what you feel. Research on spinal needles has shown that the force required to puncture the dura, the membrane surrounding the spinal cord, directly predicts the sharpness of the sensation the operator feels through their hands and, correspondingly, the jolt the patient may notice. Higher puncture force correlates with a more distinct “click” that the physician recognizes as confirmation of correct placement.3PLOS ONE. Recognition and differentiation of dural puncture click sensation: A subjective and objective prospective study of dural puncture forces using fine-gauge spinal needles From the patient’s perspective, this translates to a brief, sharp pressure that resolves almost immediately.
The Role of Anxiety
If you have been dreading the appointment for days, you are not alone, and that dread can genuinely make things worse. Pre-procedural anxiety is recognized in the pain-management literature as a factor that amplifies the experience of spinal interventions. Clinicians who perform these procedures are increasingly encouraged to screen for and address anxiety before the needle comes out, because a highly anxious patient tends to tense up, which can make positioning harder and the injection itself more uncomfortable.4Techniques in Orthopaedics. Psychological Aspects in Spinal Interventions
One approach that has shown promise for calming nerves before the procedure is watching a brief relaxation video, either on a screen or through a virtual reality headset. In one controlled trial at an outpatient spine clinic, patients who watched a nature-themed relaxation video before their injection had lower anxiety scores going into the procedure compared with those who received no video, even though the intervention did not significantly change the pain scores after the injection itself.5PubMed Central. The use of virtual reality for Peri-procedural pain and anxiety at an outpatient spine clinic injection visit: an exploratory controlled randomized trial The takeaway: reducing your anxiety going in may not erase the physical sensation entirely, but it can make the overall experience feel much more manageable. Slow breathing, distraction techniques, or simply asking your provider to talk you through each step can serve a similar purpose.
What Happens in the Hours and Days After
The needle itself is only part of the story. Once the local anesthetic wears off, usually within a few hours, you may notice a dull ache or soreness at the injection site. For most people this is mild and fades within a day. But a subset of patients experience what clinicians call a post-injection pain flare: a temporary spike in pain that can feel worse than what you walked in with.
A prospective study tracking 140 patients after musculoskeletal corticosteroid injections found that about one in five reported a flare of pain following the procedure. The good news is that these flares are short-lived. Among patients who ultimately got relief from the injection, roughly 60% noticed improvement within three days, and over 93% had meaningful pain relief within a week.6PubMed Central. Prospective Evaluation of Pain Flares and Time Until Pain Relief Following Musculoskeletal Corticosteroid Injections So if your back feels worse the night of the injection, that does not mean the procedure failed. Ice, rest, and over-the-counter pain relievers are usually enough to ride it out.
Headache is another possible side effect, particularly with epidural injections. A post-dural-puncture headache can occur if the needle creates a small leak of spinal fluid, typically causing a headache that worsens when you sit or stand and improves when you lie flat. These headaches are uncommon with modern technique and needle design, and they usually resolve on their own within a few days. One case report highlights that not every headache after an epidural injection is actually caused by the injection itself. A patient developed a headache five days after a lumbar epidural steroid injection that turned out to be caused by a medication side effect, not by the procedure.7PubMed Central. Another cause of headache after epidural injection The broader point is worth keeping in mind: if you develop unusual symptoms after a spinal injection, mention all your medications to your provider rather than assuming the injection is to blame.
Does It Matter How You Are Positioned
Your body position during the injection affects both comfort and effectiveness, and clinics handle this differently. For caudal epidural injections, which target the lower end of the spinal canal, lying on your side may be more comfortable and more effective than lying face down. A study comparing the two positions found that patients injected while lying on their side had better pain relief and improved functional scores compared to those treated in the prone (face-down) position, likely because gravity helped concentrate the medication on the affected side.8PubMed Central. Impact of Position on Efficacy of Caudal Epidural Injection for Low Back Pain and Radicular Leg Pain Due to Central Spinal Stenosis and Lumbar Disc Hernia
When a sitting position is required, as it sometimes is for lumbar injections, even small adjustments matter. A trial comparing traditional sitting with legs dangling over the side of the table versus sitting with legs extended straight on the table found that patients in the legs-on-table group were significantly more comfortable.9PubMed Central. Comparison of ease of induction of spinal anaesthesia in sitting with legs parallel on the table versus traditional sitting position If you find yourself sitting on the edge of a table with your feet on a stool and it feels unstable or awkward, ask whether you can reposition. Comfort during the setup directly affects how tense your muscles are when the needle goes in.
Virtual Reality and Sedation as Comfort Options
For patients who are especially apprehensive, two comfort strategies have gained research support in recent years: conscious sedation and virtual reality. The randomized trial mentioned earlier compared both approaches head-to-head for epidural steroid injections. Sedation lowered procedure-related pain by about 2 points on the 10-point scale compared to local anesthesia alone, and virtual reality lowered it by about 1.5 points. The two approaches did not differ from each other in a statistically meaningful way, meaning VR performed roughly on par with sedation for managing procedural pain.2The Lancet Regional Health – Southeast Asia. Virtual reality compared to sedation and standard local anesthetic for pain and anxiety during epidural steroid injections
Virtual reality has also shown striking results for lumbar punctures, a related but distinct needle-in-the-spine procedure. A randomized trial found that patients using immersive VR during lumbar puncture reported an average pain score of about 2.5 out of 10, compared to about 8.4 in the control group.10PubMed Central. Effect of immersive virtual reality on pain and anxiety during lumbar puncture: A randomized controlled trial That is an enormous gap, and while lumbar punctures are not the same as spinal steroid injections, the results suggest that immersive distraction has real physiological effects on how the brain processes procedural pain. VR headsets are still far from standard equipment in most pain clinics, but availability is growing, and it is reasonable to ask your provider whether the option exists.
Sedation, when offered, typically involves a mild intravenous medication that keeps you relaxed and drowsy but conscious. It adds cost, requires monitoring equipment and staff, and means you will need someone to drive you home. VR avoids those logistical burdens, which is one reason researchers are interested in it as an alternative.
Do Different Types of Spinal Injections Hurt Differently
There are several kinds of spinal injections, and patients often wonder whether one type is worse than another. The two most common categories are epidural steroid injections, which deliver medication into the space around the spinal cord, and facet joint injections, which target the small joints between vertebrae. A retrospective study comparing facet joint injections to transforaminal epidural steroid injections in patients with cervical nerve pain found no significant difference in outcomes at one, three, or six months, and neither technique emerged as clearly superior.11PubMed Central. Facet Joint Versus Transforaminal Epidural Steroid Injections in Patients With Cervical Radicular Pain due to Foraminal Stenosis: A Retrospective Comparative Study While that study focused on treatment outcomes rather than procedural pain, the clinical consensus is that the discomfort of the injection itself is broadly similar across types. The depth of the target and the amount of tissue the needle must pass through can vary, but local anesthetic covers the path in each case.
The choice between ultrasound guidance and fluoroscopy (a type of live X-ray) during the injection is another factor patients sometimes ask about. A prospective trial comparing ultrasound-guided and fluoroscopy-guided caudal epidural injections found no significant difference in pain relief or disability improvement at two and twelve weeks. Two cases of accidental intravascular injection occurred in the fluoroscopy group and none in the ultrasound group, though the overall complication rates were not statistically different between groups.12PubMed. Ultrasound-guided vs. fluoroscopy-guided caudal epidural steroid injection for the treatment of unilateral lower lumbar radicular pain: a prospective, randomized, single-blind clinical study From a comfort standpoint, ultrasound guidance avoids radiation exposure, while fluoroscopy provides a different kind of real-time image. Neither method is inherently more painful for the patient.
Platelet-Rich Plasma Injections and the Early Flare
Corticosteroid injections remain the most common spinal injection, but platelet-rich plasma (PRP) is gaining interest as a regenerative alternative. PRP is made from your own blood: a sample is drawn, spun in a centrifuge to concentrate the platelets, and then injected into the affected area. Because PRP contains both inflammatory and anti-inflammatory molecules, researchers have noted a pattern where PRP injections may cause more discomfort in the first few days compared to steroid injections, which tend to provide more immediate relief. The initial lesser effect of PRP is thought to result from its inflammatory mediators, with anti-inflammatory benefits kicking in later.13PubMed Central. Lumbar Transforaminal Injection of Steroids versus Platelet-Rich Plasma for Prolapse Lumbar Intervertebral Disc with Radiculopathy: A Randomized Double-Blind Controlled Pilot Study
If your provider recommends PRP over a traditional steroid injection, it is worth knowing that the first few days may be rougher. The trade-off, at least in theory, is that PRP may promote tissue repair rather than simply suppressing inflammation. The evidence for PRP in spine injections is still in its early stages, and most of the published trials are small, so expectations should be tempered accordingly.
Needle Gauge and Why It Matters
Needle size is something patients rarely think to ask about, but it has a direct relationship to what you feel. Needles are measured in gauge, and counterintuitively, a higher gauge number means a thinner needle. A 27-gauge needle is much finer than a 23-gauge needle. For procedures involving dural puncture, a randomized trial comparing 23-, 25-, and 27-gauge pencil-point spinal needles found that all three produced better early pain relief than a standard epidural technique, but the 23- and 25-gauge needles provided somewhat superior analgesia compared to the 27-gauge within the first ten minutes.14PubMed Central. Dural puncture epidural technique with 23-, 25- or 27-gauge pencil point spinal needles versus standard epidural technique for labor analgesia: a randomized trial That study was conducted in the context of labor analgesia rather than spinal pain injections, but it illustrates a general principle: needle selection is a clinical decision that balances the ease of medication delivery against patient comfort and technique precision. The thinnest needle is not always the best choice if it means the medication cannot be delivered as effectively.
Modern pencil-point needle tips, which part tissue fibers rather than cutting through them, have also reduced the risk of post-dural-puncture headache compared with older cutting-tip designs. If you are having an epidural injection and are concerned about headache risk, the needle tip design matters more than the gauge alone.
How to Prepare for Your Appointment
Practical preparation can make the experience easier in ways that have nothing to do with the injection itself. Wear loose, comfortable clothing that allows easy access to your back. Arrive a few minutes early so you are not rushing and already stressed. Ask the clinic in advance whether you should stop blood thinners or anti-inflammatory medications before the procedure, as some providers require a brief washout period. Eat a light meal beforehand; showing up on an empty stomach can make you lightheaded, which compounds anxiety.
During the procedure, focus on slow, steady breathing. Holding your breath or bearing down tenses the paraspinal muscles and can make needle advancement more uncomfortable. If you feel a sharp or electrical sensation shooting down a leg, tell the provider immediately, as this usually means the needle is near a nerve root and needs slight repositioning. After the procedure, plan to take it easy for the rest of the day. Most clinics recommend avoiding strenuous activity for 24 to 48 hours, though walking is generally fine and even encouraged.
Many patients report that the anticipation was worse than the actual injection. Knowing what each step feels like, understanding that a post-injection flare does not mean failure, and having a plan for the hours afterward all help close the gap between what you imagine and what actually happens on the table.
