jen kate,
i'm going for GA c sec. but i didn't opt for it. i've slipped disc and scoliosis so it's the only way out for me. you won't feel the pain for both c secs. just that for epi c sec, you can feel the pressure when they pull your wound open and when they tug bb out. they'll let you know all these. also, after the op, you won't be able to feel your legs and all from waist down.
for GA, after the op, you have to go to a recovery for a couple of hours. i think according to my hb, i was there for abt two hours. after that, the nurses will pat you on the face or tap you on the shoulder to make sure that you're awake and then they will wheel you back to the ward. but you'll still be very very drowsy. for my last GA op, i was like drowsy for two whole days coz of the drip where they put in my painkillers also.
if you want to breastfeed immediately after op, GA wouldn't allow you to do that. i didn't breastfeed until the middle of the night for my last surgery.
hope my info helped.
