I've never had a baby but I have had a kidney stone. Whooowh. The pain was so bad that when the E.R. nurse asked me my name I couldn't get it out legibly. So my co-worker told her. (I got up---the nurse didn't know where I was going---stepped to the bathroom, threw up and came back.) She then asked for my address. I couldn't say it either. I fumbled in my back pocket, somehow got my wallet out and was attempting to get to my drivers license out to show it to her when she said, "Follow me. I'm taking you back, now!" That sounded good to me.
I made it to a gurney. She left. My buddy asked if it was getting any better. I shook my head "no" as I squirmed, grunted and kept trying to breath while waiting on the nurse to get back. She did and gave me morphine. What a relief it was. Alka-Seltzer has nothing on that stuff.
I'm not saying it's as bad as childbirth, but it hurts.
