Epidural Injection

Treating eye and vision conditions

What is the epidural space?
The covering over the nerve roots in the spine is called the dura. The space surrounding this dura is the epidural space. This space is commonly used to deliver medications to the spine. Nerves travel through the epidural space before they travel down into your arms or legs. The nerves leave the spine from small nerve holes. Inflammation of these nerve roots may cause pain in your neck regions including shoulders and arms, and the lower back regions including the buttocks and legs. These nerve roots may become inflamed due to irritation from a damaged disc or from contact with bone spurs.

What is an epidural injection and why is it helpful?
An epidural injection places anti-inflammatory medicine into the epidural space to stop inflammation of the nerve roots, therefore reducing the pain in the affected area. By stopping or limiting nerve root inflammation, we may be able to reduce your pain. The epidural injection may assist the injury to heal by reducing inflammation. Although not always helpful, it usually reduces pain and improves function within three to seven days. It may provide permanent relief or provide a period of pain relief that will allow other treatments like physical therapy
or chiropractic treatment to be more effective.

What will happen to me during the procedure?
While lying face down on an X-ray table your skin will be well cleaned. The physician will numb a small area at the site of the injection which may sting for a few seconds. Next, the physician will use X-ray guidance to direct a small needle into the epidural space. There will be pressure felt with this part of the procedure. He will then inject contrast dye to confirm that the medicine spreads to the affected nerve root(s) in the epidural space. After this, the physician will inject a combination of numbing medicine and antiinflammatory steroid.

What happens after the procedure?
A dressing may be applied to the injection site. You will remain in the office for about 15 to20 minutes and the nurse will monitor your blood pressure and pulse. The nurse will review your discharge instructions and you will be able to go home. You may experience numbness or weakness for a few hours after the procedure. If this happens do not walk without assistance. Your physician may refer you to a physical therapist while the anti-inflammatory steroid is still working.
