When the nerves that exit the spine get compressed or irritated—for example from a disc herniation—numbness, tingling, pain and muscle weakness can result. When this occurs in the lower back, patients experience sciatica—back pain radiating into the leg with neurologic symptoms.
Epidural injections place medication around the irritated nerves. While most people think of epidurals for pregnancy, this procedure can be an effective treatment to reduce nerve root pain.
The skin and underlying tissue is numbed with an injection of local anesthetic (Lidocaine). Using moving x-ray image guidance (fluoroscopy), a larger needle is placed in a safe area just adjacent to the irritated nerve. A small amount of contrast dye is injected to assure correct placement. Then a small volume of corticosteroid (cortisone) plus local anesthetic is injected right near the nerve to maximize the benefit of treatment.
The procedure takes approximately 30 minutes to perform and after the procedure, you may remain at the clinic another 15-30 minutes. If you feel anxious about the procedure, we can provide oral medication to be taken before the procedure, with driving and other restrictions.
