This happened to my sister when she was pregnant, and I don't know of anything that helped her. It could be a pinched nerve...I got a pinched sciatic nerve when I was pregnant and the pain would bring me to tears sometimes. Could it be heartburn? I got horrible heartburn towards the end of my pregnancy, basically the weight of the baby pushes stomach acid up and it just sits there. My doctor told me to try liquid maalox for the heartburn...perhaps you could try that next time the pain happens and see if it helps. Pregnancy definitely can cause discomfort, but the end result is worth it
