Extreme pain since epidural?

I had my son 6 months ago but since he was born I've had horrible back pain. It's just gotten to the point I'm having trouble getting off the floor and picking up my son. The anesthesiologist messed up when he was putting it in and it hit a nerve and went up my body . Idk if that's what caused this pain? I'm also 6 weeks pregnant. Has anyone else experienced this? Idk what to do ? I'm in so much pain I can't play with my son and pick him up. Any suggestions?
