Surely it's impossible to say that an epidural should always be avoided or always be had, as all labours are different.
When I had my first child 14 years ago I begged for pain relief and was given an epidural, which slowed things down a LOT, everything stopped and when it came to it I wasn't able to push. There was still pain there so I just shouted for the midwives to get "the thing" out of me. 32 hours in total, forceps, lots of stitches and could not sit down for 3 weeks afterwards. Not great.
Next time, 11 years ago, I was TERRIFIED because of my first experience. However by now I had a bad case of symphis pubis and was virtually unable to walk and in a lot of pain so was induced early, and I was told I needed an epidural because of the considerable amount of pain I was in even BEFORE labour had started. So they gave me a drip, set the epidural up, I read some magazines, watched some telly, fell asleep. Woke up, felt a bit of pain, the epidural was topped up, fell asleep again. Some time later the midwife came in, woke me up, lifted the sheet and said "Oh, I can see the head!" and 6 minutes later my daughter was born easy as anything with no pain whatsoever during the entire process! (In fact I felt less pain than during the pregnancy!)
Third time, 6 years ago, I'd READ about walking epidurals but was told it was not available. Again had to be induced due to symphis pubis which by then was so bad I was wheelchair bound if I had to go out, for the last 6 weeks it was strict bed rest and loads of pain. However there was no time for an epdiural then, in fact there wasn't time for anything. Got the drip to induce me, and the gel, nothing happened, no contractions, until I had a bath after a few hours, got out of the bath and oops, there was the contractions! 5 minutes later my son was born and he literally shot out like a rocket, I had burns inside me it was that fast.

So all very different, one epidural rubbish, one fantastic, third one never needed.
