I have had good luck and no luck with the epidural injections. I have had them on my neck and my back. I have had the first one on my neck not work very well and then the second and third work well, but its vital you communicate with your doctor. When the first one on my neck did not work, he changed the location, that is why I acheived better results the second time. But, everyone is different. I have had a epidural steriod injection last one week and I have the pain relief last as long as two months, like I said everyone is different.
