i had an epidural with DD and an emcs, after going in fully expecting a straightforward labour and delivery, first pregnancy, no problems at all. waters broke on due date, and i only got to 7cm within 48 hours, at which point they said she had to come out, because of infection risk.
i think go in with an open mind - i am a needle phobe, but after about 36 hours of contractions demanded an epidural. at that point i wouldn't have cared if someone had said i would never have use of my legs again, frankly. by the time you feel you need one, you won't be worried about moving afterwards. i had it topped up for the CS, obviously. up until that point i could sort of feel my feet, but couldn't move my legs
anyway, DD was delivered around midnight and i could move VERY SLOWLY by the next afternoon, but it was the CS pain that stopped me rather than the epidural
unfortunately there were no little chairs in the shower. in fact, in my hospital, the showers were helpfully quite a high step up off the ground. how i cursed as i was left to shower alone
not sure if this is always the case, but my hospital's MLU is attached to the labour ward in any case, so if i'd gone in there and needed intervention and more drugs, they would have just transferred me
