This injection relieves pain caused by a pinched nerve (or nerves). Conditions such as herniated discs and spinal stenosis can compress nerves, causing inflammation and pain. The medication injected helps decrease the swelling of nerves.
Using x-ray guidance, also called fluoroscopy, the physician guides a needle to the painful area. Contrast dye is injected into the space to make sure the needle is properly positioned near the irritated nerve or nerves.
A combination of an anesthetic and cortisone steroid solution is injected. The steroid is an anti-inflammatory medication. It is absorbed by the inflamed nerves to decrease swelling and relieve pressure. The needle is removed and a small bandage is applied.
