What is causing my stomach pain? ive had it for 3 days along with chills/loss of appetite. im having normal bowel movement. no blood. i do have an umbilical hernia i feel discomfort when taking deep breaths/moving. stomach is sensitive when touched?

If one in her 20's has moderate tummy pain, but is normally in good health and is not pregnant, possibilities include: appendicitis (usually lower R tummy), gallstone (usually upper R tummy), kidney stone (very painful), constipation (crampy), tumor, intestinal infection, etc... A person with 3 day's of pain can get a doctor's examination to be sure it is not something serious, like a gallstone.
