Back-to-Back Labour
I had two labours myself with posterior positioned babies. I, too, was asking for pain relief before I got to 1cm dilatation.
Women who have experienced both will tell you that the posterior one was longer and more painful.
Women whose babies are posterior do have longer labours, and they are more likely to ask for epidurals and, indeed, any form of pain relief, early on in the proceedings.
Not all this pain is felt in the back, though. For some women, it is, and for others, it is felt in the back and the front.
The labour takes longer because the baby has some rotating to do before it can be delivered. Some babies do not rotate and are born facing upwards.
The shape of some women's pelvises make OP labour more likely. The doctor or midwife can assess the shape of your pelvis while you're in labour.
You asked about birthing pool/gas and air being realistic - yes, to start with. Both would probably help a woman to cope with labour, although very many women do ask for an epidural.
I asked for pethidine and gas and air and was given both, but I chose my midwife in advance! Some women (a good many on this thread, in fact) are told that it's "too early" for pain relief. I have discussed this elsewhere but I repeat, it is not good practice to deny a woman any kind of pain relief.
I'm sorry you experienced this. Please ask for a debrief and find out what your hospital's policy is about this. Women need to make their voices heard.
