It happened to me too, I found that in order to sleep without waking up in pain I had to prop myself up on my side with pillows so that I didn't roll onto my stomach or back. I had a system with four pillows that kept me on my side - DH laughed at my 'nest', but it was the only thing that helped.
If I did roll off my side, I woke up in such pain that I'd head straight for the shower and run hot water over my back to loosen up the muscles. Try a heatpack or hot water bottle, it helped me.
