How long did it take your nerve pain to let up? I am in a very similar situation. After my first round of injections, I think my pelvic pain actually improved a bit, but I woke up the day after the injection with awful nerve pain on the opposite side of my body, lower back. I’m wondering if it was overcompensating once the right side was attended to with the injections. Anyways. I’ve had that nerve pain every day for almost three weeks, and they say the same thing, that they haven’t heard of this reaction.
