Throwing up 3 days ago and whole stomach hurt, next day only lower right abdomen hurt just with movement and still hurts, and today i got diarrhea ?

See a doctor.: Pain and tenderness in the right lower part of your abdomen can be a serious problem. Possibilities include appendicitis, which is an emergency, and is often accompanied by vomiting, diarrhea, pain that begins around the belly button or all over and then moves lower and to the right, and a fever. STDs or ovarian problems can also cause this pain, but usually not vomiting or whole-belly pain.
