Epidural Spinal Injections
An epidural spinal injection is a non-surgical treatment option that may provide either short- or long-term relief of radiating back pain.
When spinal nerves become irritated or inflamed due to a degenerative condition in the spine that is causing nerve compression, such as a herniated disc or spinal stenosis, the result may be severe acute or chronic back pain, as well as pain, numbness and muscle weakness that extends elsewhere into the body, such as the hips, buttocks or legs. Before your doctor considers spine surgery to relieve these symptoms, he or she will most likely recommend one or more non-surgical treatment measures. An epidural spinal injection is one of these options.
What Is An Epidural Spinal Injection?
An epidural spinal injection involves delivering anti-inflammatory medication – typically a steroid combined with an anesthetic – directly into the area around the irritated spinal nerves that are causing the pain. This area is called the epidural space, and it surrounds the sheath-like protective membrane – or dura – that covers the spinal nerves and nerve roots. Steroids reduce nerve irritation by inhibiting production of the proteins that cause inflammation; the anesthetic blocks nerve conduction in the area where it’s applied, numbing the sensation of pain.
Why Do I Need This Procedure?
An epidural spinal injection may be done either for diagnostic or therapeutic reasons:
It’s important to note, however, that an epidural spinal injection is typically not considered a “cure” for symptoms associated with spinal compression. Rather, it’s a treatment “tool” that a doctor can use to help ease a patient’s pain and discomfort as the underlying cause of the problem is being addressed through a rehabilitative program such as physical therapy, or while the patient is considering his or her surgical treatment options.
How Is An Epidural Spinal Injection Administered?
Many hospitals and medical centers have pain management physicians who perform epidural spinal injections for conditions such as spinal stenosis, disc herniation and arthritis in the facet joints of the spine. The types of physicians who administer these injections include physiatrists, anesthesiologists, radiologists, neurologists and surgeons.
An epidural spinal injection is generally done on an outpatient basis, either at your doctor’s clinic or local hospital or medical center, and the procedure typically involves:
The procedure typically takes 15-30 minutes. After the procedure, you’ll be monitored for about 30-60 minutes in the recovery room. You should not drive following your injection; please have an adult driver available to take you home and to do any errands you may need that day. You also should avoid any strenuous activities for the rest of the day following your procedure. Your doctor also will have more specific after-care instructions for you; please follow his or her directives carefully to maximize your recovery potential.
How Long Will It Take Me To Recover?
After your injection, you may experience some numbness in your arms or legs. This is a temporary side effect associated with the anesthetic component of the injection, and it typically subsides within 1 to 8 hours. Your pain also may increase over the following 24-48 hours; it generally takes 24-72 hours for the pain-relieving benefits of a spinal epidural injection to take effect.
If your injection resolves your pain for a short period of time, you may be interested in another injection. Most doctors, however, limit the number of steroid injections they will give within a certain period of time – three per year is a common guideline. Most spine surgeons do not believe that repeated and frequent injections are a good way to manage a spine problem in the long-term. Rather, if an injection helps to relieve the pain, at least temporarily, it may indicate that surgery will be successful in helping to obtain a permanent solution for the pain.
Are There Any Potential Risks Or Complications?
As with any procedure, there are always certain risks involved with epidural steroid injections. Potential complications may include:
Complications are not a common occurrence; however, because they are potentially much more severe in the cervical spine than in the lumbar spine (low back), many physicians recommend oral steroids instead of cervical epidural spinal injections because of these risks.
Additional risk factors to consider before having an epidural spinal injection include:
Please consult your physician for a complete list of indications, warnings, precautions, adverse effects, clinical results and other important medical information that pertains to an epidural spinal injection.
