Abdominal muscles around organs, internal organs: intestines, both small and large ascending colon, including the initial, small portion called the appendix. Odds are the vitamins far less important than many other issues, what you have been eating, internal coordination of intestines, possible dehydration, constipation, emotions, infection, etc.
