An mri showed gallstones about a month ago. the past couple of nights i've woken up with stomach pain i've never had, could it be gallstone problems?

Yes : Absolutely it could be .Discuss this with iu physician.

Yes possibly: Gallstones can cause symptoms of pain, nausea and vomiting. The pain generally is felt in the upper right abdomen, but can also be felt more toward the middle. The pain can go away on its own and be colicky in nature. Typically people describe symptoms that happen after meals, but the pain can happen anytime for no reason at all. I would see your physician and you may need further testing.

?Gallbladder Attack?: Gallbladder attacks typically occur in the upper-mid abdomen or right-upper abdomen. The pain is typically a constant/steady pressure-like pain; non-burning/non-cramping. It often occurs after eating (esp. Fatty foods), last for an hour or more, are assc. W/nausea +/- vomiting, and may radiate into the back. I recommend that you see your primary care doctor for formal evaluation.
