I'm not sure about epidural, but the IV doesn't hurt too bad - as long as they do it right. I was freaking out because I had to get one on Wednesday when I went into the hospital. I'm not gonna lie, mine DID hurt but that's only because she kept pushing it in farther and farther and wouldn't stop when I said it hurt. But once the other nurse came and did it, it didn't hurt at all. Soo yeah it shouldn't hurt! Good luck!
(and I don't mean to scare you by telling you that!)
