I had my first ever steroid injection today. The epidural medication they put in felt great, although it only lasted for about 30 minutes. I was told it would last 2-4 hours. So, I had a very brief moment of relief before the pain began to return, and now I am in unbelievable pain. I know this is normal, but the pain is the worst on the right side, and they did the injection on the left. Also, I am feeling it very strongly in my mid back, whereas I usually only feel pain in the bottom half of my body. I also feel like I am going to throw up. I have felt nausiated before due to the pain, but this is different, like I might actually throw up. My vicodin isn't helping at all. Does anyone have any insight?
