Could anyone describe their experiences with a 'walking epidural', or point me to any information on them? I had been preparing to try to do without an epidural (first baby, older mother, very nervous), because I deal much better with pain and stress when I can move around, walk and change position, and someone mentioned to my partner the possibility of an epidural where it was still possible to move around - is this too good to be true, as I suspect? Or when they say 'move around', do they just mean changing your position on a bed...?
