I have a very sharp pain in my right lower stomach next to my hip should i go to the emergency room?

Some possibilities: If one has very uncomfortable tummy pain, and is normally in good health, plus is not pregnant, the possibilities include: appendicitis (usually has fever), gall stones, constipation (crampy), stomach flu, ovary problem, etc... Most people with "sharp pain," meaning more than mild pain, need a doctor's evaluation to be sure it is not appendicitis, which would need surgery.
