"Cleo - we are not talking about doctors forcing women to have epidurals they don't want".
No - I'm talking about doctors being instrumental in creating systems of maternity care which make labour unbearable for women. For me it's the elephant in the room in any discussion about pain relief in labour, whatever it is. You can't talk sensibly about epidurals without acknowledging the social context in which women are giving birth and how it impacts on their ability to cope with labour pain.
"We are talking about women who request it (like the OP and many others) who have it denied".
I assumed we were all in agreement that if women request an epidural, it's available, and it's safe to site it, then she ought to have it!
Anyone NOT agree with this? 
"You obviously have strong feelings about natural birth and that's fine - when you have a baby go for it. Other women, however, who don't share your ideas, have a right to have their views respected".
Had my three births and have done with all that now (thankfully). Would have to say though, my experience is that most women who want epidurals get one. On the other hand, the women like myself who want to give birth without pain relief and want one to one care, freedom of movement, the chance to use water in labour, or the chance to have their baby at home, face huge obstacles when it comes to realising their birth choices. I had to pay out my own pocket because my choices (to be looked after by a midwife I knew and to have my baby at home) were simply not available to me on the NHS, despite the fact that both these things were clinically and emotionally instrumental in me having a safe and satisfying birth.
On the other hand, had I wanted an epidural (and even in my case a planned c/s given my g/d and enormous baby)I assume I would have been given one without too much of a struggle.
