I'm sixteen and female. For the past two or three years I have had frequent stomach pains that normally occur soon after eating. They move from different areas of my abdomen but are worst under my right rib cage and lower left abdomen. There will periods where I will always be hungry (eating a full mean around every three hours and waking up to a rumbling empty stomach in the middle of the night) and ones where I have no appetite and have these pains. They can last for up to two hours and sometimes are so bad that I can't move. My doctor's suggestion was that we record what I eat and see if we can find a pattern, foods that trigger these problems, since they do not happen consistently. I have a very irregular period ( i once waited 11 months between menstruation) and problems with asthma. Otherwise I'm healthy and my family has no history of diseases or allergies.
