For my first emergency c/s I already had the epidural in place so they just topped it up. I could feel a burning, tearing feeling towards the end after my son was already born, so when they were packing everything away so to speak. Fortunately though they topped up the epi & I was fine. This time I had laboured without an epidural so they did a spinal block. For me it was so much better, I had no feeling whatsoever and even the tugging / pulling seemed less with the spinal than with the epi.
