A shot of cortisone is injected into the outermost section of the spinal column, the epidural space. When the adrenal gland releases it, cortisone suppresses the immune system, dimming inflammation and, in turn, our perception of pain. Naturally-occurring cortisone is short-acting. Artificial cortisone, like that delivered in an epidural steroid injection, is designed to last for much longer—anywhere from a few weeks to months.
The goal is to kill off as much bacteria as it can around the damaged site before it needs to call in reinforcements. So if the inflammation goes on for an extended period of time, it causes pain. When cortisone is released by the adrenal gland, it has the opposite effect—it suppresses the immune system in a targeted area, reducing inflammation and thus reducing the associated pain.
But instead of waiting for the cortisone to release on its own, your doctor is giving you a concentrated dose of artificial cortisone to hold the pain at bay for an extended period of time. Epidural steroid injections contains cortisone that acts as an anti-inflammatory agent. It creates an overall pain-relieving effect for an extended period.

These headaches typically get worse before they get better.
