Epidural steroid injections are performed at pain management clinics, ambulatory surgery centers, hospital outpatient departments, and some orthopedic or neurosurgery offices. The procedure takes about 15 to 30 minutes and is done on an outpatient basis, meaning you go home the same day. Finding the right provider depends on your location, insurance, and the specific spinal condition being treated.
Types of Facilities That Offer ESIs
Most epidural steroid injections happen in one of three settings. Dedicated pain management clinics are the most common. These are standalone offices or practices staffed by physicians who specialize in spine-related pain procedures. They typically have the imaging equipment needed to guide the needle precisely into the epidural space.
Ambulatory surgery centers are another option. These are outpatient facilities designed for procedures that don’t require an overnight hospital stay. Many hospitals also operate satellite ambulatory care centers in surrounding communities, so you may not need to visit the main hospital campus. Hospital outpatient departments offer the same procedure, often within a pain management or interventional radiology suite. Hospital-based settings can be more expensive due to facility fees, but they may be the only option for patients with complex medical histories who need extra monitoring.
Which Specialists Perform the Injection
Several types of physicians are trained to perform epidural steroid injections. The most common include physiatrists (physical medicine and rehabilitation doctors), anesthesiologists with pain management fellowships, interventional radiologists, neurologists, and spine surgeons. A physiatrist or pain management anesthesiologist is typically who you’ll see if your primary care doctor sends you to a pain clinic.
What matters more than the specialty title is that the physician uses imaging guidance during the procedure. Without real-time imaging, incorrect needle placement rates are strikingly high: up to 30% for lumbar injections, 53% for cervical injections, and as high as 50% for caudal injections performed at the base of the spine. Fluoroscopy (a type of live X-ray) is the standard of care. It allows the physician to watch the needle on screen and confirm placement with a small amount of contrast dye before injecting the steroid. Any provider you choose should use fluoroscopy or CT guidance routinely.
How to Find a Provider
The most direct path is a referral from your primary care doctor. Most insurers require one, and your doctor can match you with a specialist based on your diagnosis and imaging results. If you have an MRI or CT scan showing a herniated disc, spinal stenosis, or nerve compression, bring those results to your consultation. If you don’t yet have imaging, your specialist will likely order it before scheduling the injection.
To search on your own, look for “pain management” or “interventional spine” practices in your area. Your insurance company’s provider directory is a practical starting point because it filters for in-network physicians. Hospital systems often list their pain management services online with specific locations. When calling a clinic, ask whether the physician uses fluoroscopic guidance and how many ESIs they perform regularly.
What’s Required Before You Can Get One
Epidural steroid injections aren’t a first-line treatment. Medicare guidelines, which many private insurers mirror, require that you’ve had pain for at least four weeks and that you’ve either tried conservative treatments (such as physical therapy, oral medications, or activity modification) for four weeks without adequate relief, or that you’re unable to tolerate those treatments. An exception exists for conditions like acute shingles pain, where the four-week waiting period isn’t required.
You’ll also need a confirmed diagnosis supported by imaging. An MRI of the affected spinal region is the preferred study, with CT used as an alternative when MRI isn’t available. The imaging needs to show a structural cause for your pain, such as a disc herniation pressing on a nerve root, that matches your symptoms and physical exam findings. Your specialist will review all of this before deciding whether an ESI is appropriate.
Two Main Injection Approaches
Physicians use two primary routes to reach the epidural space: interlaminar and transforaminal. The interlaminar approach enters between the bony arches of the vertebrae and delivers medication broadly into the epidural space. It’s the more traditional technique and is widely performed. The transforaminal approach threads the needle alongside a specific nerve root as it exits the spine, delivering a concentrated dose of steroid directly to the site of inflammation.
For conditions like lumbar disc herniation or pain that radiates down one leg, research suggests the transforaminal route may provide better short-term relief because it targets the exact nerve involved. One study found significantly higher rates of functional improvement with the transforaminal approach compared to interlaminar at two weeks and through six months. However, by six months the outcomes tend to converge. Transforaminal injections also require more specialized training, involve radiation exposure from fluoroscopy, and cost more. Your physician will recommend the approach that best fits your specific anatomy and diagnosis.
How Well They Work and How Long Relief Lasts
Pain relief from an epidural steroid injection typically kicks in within two to seven days. For many people, that relief lasts three months or longer. In studies of patients with disc-related leg pain, up to 70% reported at least 50% improvement at one to two months, and about 40% still felt better at 12 months. Some people experience minimal or no relief, particularly when the source of pain is not primarily inflammatory nerve compression.
When injections do work, they’re often used as a bridge. The window of reduced pain lets you engage more effectively in physical therapy and exercise, which addresses the underlying problem. Repeat injections are possible if the first one provides meaningful but temporary relief, though most guidelines limit the total number within a given year.
What to Expect on Procedure Day
The injection itself is quick. You’ll lie face down on a procedure table, and the skin over the injection site is numbed with a local anesthetic. Using fluoroscopy, the physician guides a thin needle into the epidural space, confirms placement with contrast dye, then injects a combination of steroid and sometimes a local anesthetic. You’ll be monitored for 15 to 30 minutes afterward before being discharged.
Plan for someone to drive you home. Most providers recommend one to two days of relative rest after the injection, avoiding strenuous activity to allow the medication to settle and to monitor for any reactions. You can typically return to normal daily activities within 24 to 48 hours, increasing intensity gradually. Physical therapy can usually resume within a few days, which is often the whole point of getting the injection in the first place.
Safety Considerations
Epidural steroid injections are generally safe, but they carry real risks. Common side effects include temporary increases in pain at the injection site, mild headache, and short-term blood sugar spikes in people with diabetes. Rare but serious complications include nerve damage, infection, and spinal headache from a dural puncture.
The FDA issued a safety communication in 2014 noting that rare but serious neurologic events have been reported, including stroke, paralysis, and vision loss. These events are most closely associated with a specific combination: particulate steroid formulations used in transforaminal injections, particularly in the cervical (neck) spine. A consensus group of pain specialists recommended that particulate steroids should not be used for cervical transforaminal injections, and that non-particulate alternatives are preferred in that setting. If you’re scheduled for a neck injection using the transforaminal approach, it’s reasonable to ask your physician which type of steroid they plan to use.
