Caudal Epidural Steroid Injections are a combination of a steroids and/or local anesthetics that are delivered to your lower back to treat chronic back and lower extremity pain.
The injection is performed at the base of the spine just above the tail bone or coccyx. A small needle is inserted at this location and advanced to the epidural space. The goal of the injection is to decrease inflammation of the nerve roots and other back structures, hopefully reducing the pain in lower back and lower extremities. The epidural injection may help the injury to heal by reducing inflammation. It may provide long term relief or provide a period of pain relief for several months while the injury/cause of pain is healing.
All injections are performed under fluoroscopy (x-ray), ultrasound-guidance or both.
What can you expect after the injection?
You may have some numbness around your buttock area for a few hours. Rarely, you may have a little muscle weakness in your legs for a few hours. After 24-36 hours, the steroids will begin to take effect, and you should start feeling pain relief.
Many patients who receive these injections for management of their chronic back pain enjoy improved function and diminished pain. The procedure can be repeated if required.
