I agree with what everyone has said here. As people have said take any pain killers and don't let the nurses guilt you about taking them (I had one nurse who did that). Don't be afraid to ask for help from nurses or family.

When laying in bed I found it helpful to put a pillow under my belly for support if I was laying on my side. Some people also advised me to have several pillows around you for support but I never tried that as I found the one pillow enough.
