You must see a doctor immediately to determine your symptoms' cause. It could be anything from a stomach virus to a foodborne illness to a more serious condition. Your doctor can run tests to determine the cause and provide the appropriate treatment. In the meantime, it is important to stay hydrated by drinking plenty of fluids and avoiding foods that could worsen your symptoms.
