Not that I recall. Because they're pumping so much shit in there, it may have created more pressure on the nerve. That's what I imagine would have happened if it hurts worse. I don't know how long it will take for your body to absorb the cortisone. I almost remember being told that it might hurt worse for a day or two after, but I might be making that up. If you call the doc and ask, then he'll probably be able to clear it up pretty quickly.
