Lay down in a quiet place. Put one hand on your stomach and close your eyes. Picture a healing white light going through the top of your head, down your arm, and into your stomach. As you breate in sag in your head, "Good Energy." As you breathe out say, "Bad Energy." Concentrate on only that. I know it seems stupid but it really helps. I do that when my stomach hurts and the pain goes away. It may take a while but with every time you do that, the shorter it will take to get the pain to leave.
