I have pain near my belly button extending to my right hip, nausea, chills, lethargy. what should i do? any other conditions besides appendicitis?

Some thoughts...: If one has very uncomfortable tummy pain, and is normally in good health, plus is not pregnant, the possibilities include: appendicitis (usually R lower quadrant), colitis, kidney stone (very painful), constipation (crampy), stomach flu, etc... Most people with "moderate pain", more than mild pain, may need a doctor's evaluation to be sure it is not appendicitis, which would need surgery.
