I've had an epidural during both of my deliveries. This one will be with an epidural, too. I couldn't feel a thing when they administered the epidural. I'm a real wimp when it comes to pain. I had to have the nurse give me a small shot to numb my hand before giving me the IV. That's how bad I am. If it didn't hurt me, it probably won't hurt you.
Try to not be nervous about the epidural or childbirth. With the epidural, childbirth was actually fun (I was ready to have another baby immediately after having my daughter, keep in mind, I was on drugs~the epidural).
