Depending on where a stone blocks the flow of bile, symptoms can include nausea, vomiting, fever, and severe abdominal pain that lasts longer than 6 hours. If you have these symptoms, you may need surgery to remove your gallbladder or the gallstone causing the blockage.

Stomach flu (gastroenteritis) and food poisoning also can cause symptoms similar to gallstones. Diarrhea and vomiting occur with the flu and food poisoning, but the pain tends to come and go rather than be constant.
