I went through the horrible pain when pregnant with my now 2 year old daughter. I got a pregnancy belt and since the biggest part of the problem was her sitting like a little frog on my bowels and all that's in the general area, I ate fruit loops and FINALLY got her to change positions. The fruit loops were for the sugar to get her active and once she got to moving around, I would use the belt and my hand to block her from moving back once she got to a position that was not so painful to me. I also used this method to get her to move from breach to head down about a week before I delivered.
Hope this helps.
