well it's either your appendix (had mine removed at the er visit) or it could be gallstones. i'd say it's more likely to be your gallbladder and a flare up/gallstones. my family has history of gallstones/gallbladder issues and both my parents have their gallbladder and appendix removed. my mom had the same symptoms you had and went to the er (after her pain was so bad) and had an emergency removal of her gallbladder. hope you find the answers you need.
