LadyT - Just to add my experience, in case it helps. I also had an emergency section and it was absolutely fine.
Re the epidural/spinal block - what they do is get you to sit up with your spine curled. They first give you a jab of local anaesthetic (regular injection) so when the epidural needle goes in you don't feel it. Nothing like a lumbar puncture, which can be a nasty business! If the anaesthetist gets it right (which was my experience), its no trouble at all. In fact in my case, complete bliss, as I hadn't slept for about 3 days and finally got to feel human. They also check its kicked in. The only thing to watch out for and it happened to a friend of mine, is that if they nick the membranes when the epidural goes in you can get some blinding headaches - if that happens they can patch it up very easily, just make sure you get sorted if it does!
Like traceface, have no memory at all of the catheter, so again, assume they put it in after the anasthaetic.
The op itself was pretty civilised. Everyone introduced themselves, the radio was on (madonna I think) and I remember making random small talk with the lovely anaesthetist. DH was with me on my side too. I am blind as a bat, so without glasses or contacts couldn't really see too much. When DD came out, DH went with her to see her get weighed etc while I was stitched up.
I got DD in recovery, where I think we spent about an hour or so, before moving to the ward.
Physically I was in OK shape after the op - none of the vomiting, wind, nausea problems that people talk about. No pain either - all fairly well controlled with the drugs they give you. Not that much to being examined either. The one annoying thing medically, is that after the op I had a drain (a kind of plastic container attached to me by a tube to collect gunk - lovely!). You won't necessarily need one. The doc pretty quickly confirmed I didn't need it anymore, but I had to nag and nag to get the midwives or someone to take it out - but if you're at the Lindo(?) you really shouldn't have that kind of problem.
It was really only the first day/night or so that was really a problem - bending to get up (or across to get DD) was tricky for maybe the first 24 hrs, or not even that long. I would say be shameless about calling the midwives if you need them e.g. to start with I couldn't get DD out of her cot near my bed on my own very easily - don't hestitate to shout for someone to hand her over! Although to put it all in perspective, I only spent two nights on the ward after the op and certainly by the second day I was fine to get about the ward, get washed on my own, look after DD etc etc.
All in all, it was a remarkably unscary, untraumatic, unpainful experience! The main reason I am not going straight back for a section this time is that I think an inability to pick up DD for a few days will annoy her no end and I think all our lives will be easier if we limit the disruption for her as much as possible. For my part a section seems like the easier option!
