Breathing helps a ton. Also taking a very hot shower and staying off your back as much as possible!

it hurts so bad but breathing helps a lot.

Definitely. It was alllll in my back. It was painful but I did end up having an all natural birth. The shower and "slow dancing" were the best coping methods for me.
