diaphragm spasm: Side 'stitch' is a common slang term for diaphgram spasm which occurs while running or during vigorous activitiy. The diaphragm expands and contracts during normal breathing. When you exercise, the movement is exagerated and a spasm may occur which feels like something poking you in your side.
