I haven't read through everything, but I'll post my opinion/experience, but with a disclaimer. You really have to figure out what birthing technique is important to you - I didn't necessarily feel strongly about yes to epidural or no - I decided to play it by ear - but some people DO feel strongly about it. I knew that I didn't want IV pain relief or other pain meds, but that was about it.
Yes, it hurts, but it wasn't the worst pain I have ever felt. Early labor was tightening/pressure/a little pain. I was shocked when I got to the hospital and I was at 6 cm - I had labored for about 4 hours at home. Anyway - I got "stuck" at a 6 - turns out, DD was kind of stuck herself (on the pubic bone), so she wasn't moving "down" the way she should have been. OK - long story short - after about 6 hours of labor and no progression, I said "yes" to the epidural and it was the greatest thing I ever did!
I literally slept almost all day - epidural was placed around 10 am and she was born about 6:45 pm. I don't remember sleeping so much, but we have videotaped evidence to prove it.
As for the epidural needle - I was freaked out about it DURING pregnancy, but when the time came, the Dr. was very careful not to let me see - I still don't know exactly how big it was but DH assures me it was about the size of a harpoon. I felt nothing when it was placed - a tiny prick maybe for the local anesthesia they use before the big gun comes out.
I am convinced my anesthesiologist was a genius because my epidural worked perfectly. What they may not tell you is that they turn it off when it's time to push. After about 10-15 minutes of it being turned off, I could feel the pressure of the contractions (not pain, just pressure), so I knew when to push. After DD was birthed (her favorite word!), I had to have a couple of stitches - it had worn off enough that I yelped when the Doc tried to do the first one and he was surprised I could feel it - he had to give me a local to do the stitches. I was un-numb enough within a half-hour or so that I could have walked to my room but they wouldn't let me.
And finally, finally - I was not entirely pain free I guess - at one point, DD was not in a good spot and I had horrible back pain. The epidural did NOTHING to ease that pain and it was terrible because it didn't come and go like a contraction, it was constant. However, it didn't last too terribly long (it was during the pushing phase!).
On a scale of 1-10, I'd say the pain was about an 8 - occasionally a 9. But all said, the pain would not keep me from having another child. Oftentimes, I think anticipation of the pain and process is more terrifying than the reality.
Good luck!
