Increased discomfort after eating could be due to a stomach disorder like gastritis or peptic ulcer. A gastroscopy to evaluate the stomach may need to be done. A blood test for Helicobacter pillory is also required because infection with this bacterium is usually connected with chronic gastritis. An abdominal aortal aneurism (AAA) is a serious condition and its treatment has priority above stomach examinations. That cyst on the pancreas could indicate chronic pancreatitis which can be also manifested with abdominal discomfort.


You may want to consult a gastroenterologist about this.
