Gallbladder?: If this is in the right upper abdominal area (plus minus fevers & chills) and after eating greasy/oily foods for dinner, this may be gallbladder disease. You should see your physician. In the meantime stay away from fried, oily, greasy foods. (there are of course other possibilities...Either way a visit to your physician is in order).
