An injection of a : Steroid type medication done under a local anesthesia with or without IV sedation in a sterile setting either with or without fliuroscopic or x-ray guidance into space below the lamina but above the dura or lining of the nerve tissue of the spine with the needle passing through natural openings between the lamina given for pain relief due to inflammation from a disc herniation or spinal stenosis.

Steroids epidurally: Placing medication in the epidural space allows it to bath nerves as they leave the spinal cord and also to bath tissue near the spine. Steroids are injected to reduce inflammation and swelling, and are typically used for back pain or "pinched nerve". The steroids require hours or days to achieve full effect. They steroid may be mixed with small amounts of local anesthetic.

ESI: An epidural steroid injection is a minimally invasive procedure that delivers steroids via a needle directly into the epidural space to help reduce inflammation.
